=head1 SYNOPSIS
to use them in L<Moose> code without anybody ever noticing you aren't using
L<Moose> everywhere.
+L<Moo> will also create L<Moose type constraints|Moose::Manual::Types> for
+classes and roles, so that C<< isa => 'MyClass' >> and C<< isa => 'MyRole' >>
+work the same as for L<Moose> classes and roles.
+
Extending a L<Moose> class or consuming a L<Moose::Role> will also work.
So will extending a L<Mouse> class or consuming a L<Mouse::Role> - but note
This method should always return a hash reference of named options.
+=head2 FOREIGNBUILDARGS
+
+If you are inheriting from a non-Moo class, the arguments passed to the parent
+class constructor can be manipulated by defining a C<FOREIGNBUILDARGS> method.
+It will receive the same arguments as C<BUILDARGS>, and should return a list
+of arguments to pass to the parent class constructor.
+
=head2 BUILD
Define a C<BUILD> method on your class and the constructor will automatically
die "$_[0] is not a number!" unless looks_like_number $_[0]
},
+Note that the return value is ignored, only whether the sub lives or
+dies matters.
+
L<Sub::Quote aware|/SUB QUOTE AWARE>
Since L<Moo> does B<not> run the C<isa> check before C<coerce> if a coercion
If you set this to just C<1>, the predicate is automatically named
C<has_${attr_name}> if your attribute's name does not start with an
-underscore, or <_has_${attr_name_without_the_underscore}> if it does.
+underscore, or C<_has_${attr_name_without_the_underscore}> if it does.
This feature comes from L<MooseX::AttributeShortcuts>.

is ignored.

+
+Takes either a coderef or array of coderefs which is meant to transform the
+given attributes specifications if necessary when upgrading to a Moose role or
+class. You shouldn't need this by default, but is provided as a means of
+possible extensibility.

An extension L<MooX::late> exists to ease translating Moose packages
to Moo by providing a more Moose-like interface.
