=head1 NAME
Kavorka::Manual::PrototypeAndAttributes - the more rarely used features of Perl subroutines
=head1 DESCRIPTION
=head2 The Prototype
Like with the L<sub|perlsub> keyword, a prototype may be provided for
functions. Method dispatch ignores this, so it's only likely to be
useful for C<fun>, and even then, rarely.
Like L<Function::Parameters>, Kavorka uses C<< :(...) >> to indicate
a prototype. This avoids ambiguity between signatures, prototypes and
attributes.
For compatibility with Perl 5.20, the special attribute
C<< :prototype(...) >> is supported as an alternative mechanism for
expressing prototypes.
=head2 The Attributes
Attributes are parsed as per L<perlsub/Subroutine Attributes>.
For anonymous functions, some attributes (e.g. C<:lvalue>) may be
applied too late to take effect. Attributes should mostly work for
named functions though.
=head1 BUGS
