Extending a L<Moose> class or consuming a L<Moose::Role> should also work.
+So should extending a L<Mouse> class or consuming a L<Mouse::Role>.

This means that there is no need for anything like L<Any::Moose> for Moo
-code - Moo and Moose code should simply interoperate without problem.
+code - Moo and Moose code should simply interoperate without problem. To
+handle L<Mouse> code, you'll likely need an empty Moo role or class consuming
+or extending the L<Mouse> stuff since it doesn't register true L<Moose>
+metaclasses like we do.
However, these features are new as of 0.91.0 (0.091000) so while serviceable,
they are absolutely certain to not be 100% yet; please do report bugs.
=item * is
-B<required>, may be C<ro>, C<rw>, C<lazy> or C<rwp>.
+B<required>, may be C<ro>, C<lazy>, C<rwp> or C<rw>.
C<ro> generates an accessor that dies if you attempt to write to it - i.e.
a getter only - by defaulting C<reader> to the name of the attribute.
-C<rw> generates a normal getter/setter by defauting C<accessor> to the
-name of the attribute.
-
C<lazy> generates a reader like C<ro>, but also sets C<lazy> to 1 and
C<builder> to C<_build_${attribute_name}> to allow on-demand generated
attributes. This feature was my attempt to fix my incompetence when
from inside of the class, but read-only from outside.
This feature comes from L<MooseX::AttributeShortcuts>.

L<Sub::Quote aware|/SUB QUOTE AWARE>
+Since L<Moo> does B<not> run the C<isa> check before C<coerce> if a coercion
+subroutine has been supplied, C<isa> checks are not structural to your code
+and can, if desired, be omitted on non-debug builds (although if this results
+in an uncaught bug causing your program to break, the L<Moo> authors guarantee
+nothing except that you get to keep both halves).
+
If you want L<MooseX::Types> style named types, look at
L<MooX::Types::MooseLike>.

-Coerce does not require C<isa> to be defined, but since L<Moose> does
-require it, the metaclass inflation for coerce-alone is a trifle insane
-and if you attempt to subtype the result will almost certainly break.
+Note that L<Moo> will always fire your coercion - this is to permit
+isa entries to be used purely for bug trapping, whereas coercions are
+always structural to your code. We do, however, apply any supplied C<isa>
+check after the coercion has run to ensure that it returned a valid value.

will return an appropriate metaclass pre-populated by L<Moo>.
-No support for C<super>, C<override>, C<inner>, or C<augment> - override can
-be handled by around albeit with a little more typing, and the author considers
-augment to be a bad idea.
+No support for C<super>, C<override>, C<inner>, or C<augment> - the author
+considers augment to be a bad idea, and override can be translated:

The C<dump> method is not provided by default. The author suggests loading
L<Devel::Dwarn> into C<main::> (via C<perl -MDevel::Dwarn ...> for example) and
C<auto_deref> is not supported since the author considers it a bad idea.
C<documentation> will show up in a L<Moose> metaclass created from your class
-but is otherwise ignored. Then again, L<Moose> ignors it as well, so this

Handling of warnings: when you C<use Moo> we enable FATAL warnings. The nearest
similar invocation for L<Moose> would be:
