=head1 NAME
Moo - Minimalist Object Orientation (with Moose compatiblity)
-=head1 WARNING WARNING WARNING
-
-This is a 0.9 release because we're fairly sure it works. For us. Until it's
-tested in the wild, we make no guarantees it also works for you.
-
-If this module does something unexpected, please submit a failing test.
-
-But if it eats your cat, sleeps with your boyfriend, or pushes grandma down
-the stairs to save her from the terrible secret of space, it's not our fault.
-
=head1 SYNOPSIS
package Cat::Food;
=head2 BUILDARGS
-This feature from Moose is not yet supported.
+ around BUILDARGS => sub {
+ my $orig = shift;
+ my ( $class, @args ) = @_;
+
+ unshift @args, "attr1" if @args % 2 == 1;
+
+ return $class->$orig(@args);
+ };
+
+ Foo::Bar->new( 3 );
+
+The default implementation of this method accepts a hash or hash reference of
+named parameters. If it receives a single argument that isn't a hash reference
+it throws an error.
+
+You can override this method in your class to handle other types of options
+passed to the constructor.
+
+This method should always return a hash reference of named options.
=head2 BUILDALL
C<BUILD> method from parent down to child after the object has been
instantiated. Typically this is used for object validation or possibly logging.
+=head2 DESTROY
+
+A default destructor is provided, which calls
+C<< $instance->DEMOLISH($in_global_destruction) >> for each C<DEMOLISH>
+method in the inheritance hierarchy.
+
=head2 does
if ($foo->does('Some::Role1')) {
=item * coerce
-This Moose feature is not yet supported
-
-=begin hide
-
Takes a coderef which is meant to coerce the attribute. The basic idea is to
do something like the following:
$_[0] + 1 unless $_[0] % 2
},
-L<Sub::Quote aware|/SUB QUOTE AWARE>
+Coerce does not require C<isa> to be defined.
-=end hide
+L<Sub::Quote aware|/SUB QUOTE AWARE>
=item * trigger
B<Boolean>. Set this if the attribute must be passed on instantiation.
+=item * reader
+
+The value of this attribute will be the name of the method to get the value of
+the attribute. If you like Java style methods, you might set this to
+C<get_foo>
+
+=item * writer
+
+The value of this attribute will be the name of the method to set the value of
+the attribute. If you like Java style methods, you might set this to
+C<set_foo>
+
=item * weak_ref
B<Boolean>. Set this if you want the reference that the attribute contains to
C<auto_deref> is not supported since the author considers it a bad idea.
C<documentation> is not supported since it's a very poor replacement for POD.
