-from L<Scalar::Util> are copied into this dist. L<Scalar::Util> is required if
-you'd like weak references; there's simply no way to do it from pure Perl.

nothingmuch has written L<Squirrel> (part of this distribution) which will act
as Mouse unless Moose is loaded, in which case it will act as Moose.

-Mouse also has the blessings of Moose's author, stevan.
+L<Any::Moose> is a more high-tech L<Squirrel>.
