Type constraints and coercions for Perl

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.

The author’s long-term goal is to replace Moose’s built-in types and MooseXTypes with this module.
