Import p5-Specio-0.25 as devel/p5-Specio.

The Specio distribution provides classes for representing type constraints
and coercion, along with syntax sugar for declaring them.

Note that this is not a proper type system for Perl. Nothing in this
distribution will magically make the Perl interpreter start checking a
value's type on assignment to a variable. In fact, there's no built-in way
to apply a type to a variable at all.

Instead, you can explicitly check a value against a type, and optionally
coerce values to that type.

My long-term goal is to replace Moose's built-in types and MooseX::Types
with this module.
