- New upstream release 0.25
- Calling {any,object}_{isa,does}_type repeatedly in a package with the same
class or role name would die; these subs are now special-cased to simply
return an existing type for the given name when they receive a single
argument (the name of the class or role)
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.
