+- local coerce
+
+[13:16] mst stevan: slight problem with coerce
+[13:16] mst I only get to declare it once
+[13:17] mst so if I'm trying to declare it cast-style per-source-class rather than per-target-class
+[13:17] mst I am extremely screwed
+[13:17] stevan yes
+[13:17] stevan they are not class specific
+[13:18] stevan they are attached to the type constraint itself
+[13:18] * stevan ponders anon-coercion-metaobjects
+[13:18] mst yes, that's fine
+[13:19] mst but when I declare a class
+[13:19] mst I want to be able to say "this class coerces to X type via <this>"
+[13:19] stevan yeah something like that
+[13:19] stevan oh,.. hmm
+[13:20] stevan sort of like inflate/deflate?
+[13:20] stevan around the accessors?
+[13:25] * bluefeet has quit (Remote host closed the connection)
+[13:27] mst no
+[13:27] mst nothing like that
+[13:27] mst like a cast
+[13:31] mst stevan: $obj->foo($bar); where 'foo' expects a 'Foo' object
+[13:31] mst stevan: is effectively <Foo>$bar, right?
+[13:32] mst stevan: I want to be able to say in package Bar
+[13:32] mst stevan: coerce_to 'Foo' via { ... };
+[13:32] mst etc.
+[13:53] stevan hmm
-[18:18] mst what I'd really like is just to say trigger => 'some_method'

+INTERNALS
+-------------------------------------------------------------------------------
-- attribute delgates
+- rationalize all the get_X methods for classes (and roles)
-Introduce capability to control the generated wrapper. Useful for when you have
-a wrapper that should implement the interface of it's child, but decorate with
-more metadata.
+We have get_attribute, get_attributes_list, get_all_attributes,
+etc. First, we need to make the method names consistent. If something
+returns an attribute vs a name, that needs to be clear from the method
+name. We also need to make sure that local vs. "entire inheritance
+chain" is clear from the name.
-- proxy attributes
+Finally, kill all the public get_X_map methods. The hashref it returns
+is the internal reference, and the fact that it _is_ a hashref is just
+an implementation detail.
+
+This is mostly a CMOP change.
+
+- Metaclass constructors
+
+There's a _lot_ of different conventions in here. Some things to consider:
+
+* new vs _new
+* allowing new( 'name', %args ) vs ( name => 'name', %args )
+* Method->wrap vs Method->new
+
+- Role & Class
+
+These two share a _lot_ of logic, but it's not via shared code. Maybe
+implement some sort of role-lit internal thing so we can have a
+"HasAttributes" and "HasMethods" role for classes and roles.
+
+- Moose::Meta::TypeConstraint::Parameter{izable,ized}
+
+The relationship between these two classes is very odd. In particular,
+this line in Parameterized is insane:
-[15:49] stevan you want a proxied attribute
-[15:49] stevan which looks like an attribute,
- talks like an attribute, smells
- like an attribute,.. but if you
- look behind the curtain,.. its
- over there.. in that other object
-
-- compile time extends
-
-[00:39] sri but maybe a better syntax for compile time extends
-[00:39] stevan I have been pondering that actually
-[00:39] sri use Moose extends => Foo::Bar
-[00:40] stevan I think now that we have the Sub::Exporter stuff
- in, that kinda thing should be pretty easy
-
-nothingmuch notes that all the constructs should be supported in the entirety of the use clause:
-
- use Moose (
- has => foo (
- ....
- ),
- );
-
-and that if this usage style is used nothing is exported to the namespace.
-
-- default should dclone()
-
-- subtype $anon_subtype => where { ... }
-
-[22:56] stevan sub mst_doesnt_like_to_type { (shift)->meta->attr->type_contstraint }
-[22:57] mst err
-[22:57] stevan :P
-[22:57] stevan are you wanting to reuse it or something?
-[22:57] stevan my $subtype = subtype 'Something' => where { ... };
-[22:58] stevan then you can do isa => $subtype
-[22:58] mst but I can't subtype it again
-[22:59] stevan mst: ahhh...
-[22:59] mst well, I can. but it suddenly gets very "long way round" ish
-[23:00] stevan my $constraint = Moose::Meta::TypeConstraint->new(
-[23:00] stevan name => $name || '__ANON__',
-[23:00] stevan parent => $parent,
-[23:00] stevan constraint => $check,
-[23:00] stevan message => $message,
-[23:00] stevan );
-[23:00] stevan yeah thats kinda the long way
-[23:00] stevan mst: what would you like it to be?
-[23:00] mst $parent = find_type_constraint($parent) if defined $parent;
-[23:00] mst if $parent is already a type constraint
-[23:00] mst skip that bit
-[23:00] stevan hmm
-[23:00] mst should be all you need to change
-[23:00] stevan yeah
-[23:01] stevan so you can then say
-[23:01] stevan subtype $anon => where { ... };
-[23:01] mst right
-[23:01] stevan ok
-
-- method keyword
-
-[23:37] mst more seriously, I'd still like a "method" keyword or something
-[23:37] mst method 'foo' => sub { ... };
-[23:38] stevan what would it do more than sub foo { ... }?
-[23:39] stevan I would like multimethods actually
-[23:39] mst almost exactly nothing, to begin with
-[23:39] stevan but thats just cause I love CLOS and am reading a book on Dylan now
-[23:40] stevan keyword squating :)
-[23:40] mst but if we need to hook stuff later it's bloody handy to already have people writing it that way
-[23:40] mst right
-...
-[23:49] mst oh, also: method 'has' => sub { ... } could squelch the redefine warning
+ foreach my $type (Moose::Util::TypeConstraints::get_all_parameterizable_types()) {
+
+Why does it need to loop through all parameterizable types? Shouldn't
+it know which parameterizable type it "came from"?
+
+- Moose::Util::TypeConstraints vs Moose::Meta::Type{Coercion,Constraint}
+
+The Util module has _way_ too much functionality. It needs to be
+refactored so it's a thin sugar layer on top of the meta API. As it
+stands now, it does things like parse type names (and determine if
+they're valid), manage the registry, and much more.
+
+- Moose::Meta::Role::Application::*
+
+These class names are hardcoded throughout Moose, making replacing
+them very difficult.
+
+- Moose::Meta::Role & attributes
+
+The way a role stores attributes is nasty and not very
+introspectable. It should store some sort of object, possibly one that
+knows how to turn itself into a "real" attribute.
+
+- Anything with a _(meta)?class method
+
+Every method that returns a class name needs to become a rw attribute
+that can be set via the constructor.
+
+- The Moose::Error stuff
+
+This is sort of half-implemented. We still use Carp directly, and the
+internals can't decide how to throw an error (is it
+Moose->throw_error, __PACKAGE__->throw_error, what?).
+
+The internals need to be made consistent before we expose this to the
+rest of the world.

TO PONDER
- Moose "strict" mode
use Moose 'strict'; This would allow us to have all sort of expensive tests
-which can be turned off in prod.

- Moose::Philosophy.pod
To explain Moose from a very high level
- moosedoc
We certainly have enough meta-information to make pretty complete POD docs.
