NAME ^

Kavorka::Manual::PrototypeAndAttributes - the more rarely used features of Perl subroutines

DESCRIPTION ^

The Prototype

Like with the sub keyword, a prototype may be provided for functions. Method dispatch ignores this, so it's only likely to be useful for fun, and even then, rarely.

Like Function::Parameters, Kavorka uses :(...) to indicate a prototype. This avoids ambiguity between signatures, prototypes and attributes.

For compatibility with Perl 5.20, the special attribute :prototype(...) is supported as an alternative mechanism for expressing prototypes.

The Attributes

Attributes are parsed as per "Subroutine Attributes" in perlsub.

For anonymous functions, some attributes (e.g. :lvalue) may be applied too late to take effect. Attributes should mostly work for named functions though.

BUGS ^
