This class implements the same API as Specio::Constraint::Simple, with a few additions.
Specio::Constraint::Parameterizable->new(...)
This class's constructor accepts two additional parameters:
• parameterized_constraint_generator
This is a subroutine that generates a new constraint subroutine when the type is parameterized.
It will be called as a method on the type and will be passed a single argument, the type object for
the type parameter.
This parameter is mutually exclusive with the "parameterized_inline_generator" parameter.
• parameterized_inline_generator
This is a subroutine that generates a new inline generator subroutine when the type is parameterized.
It will be called as a method on the Specio::Constraint::Parameterized object when that object needs
to generate an inline constraint. It will receive the type parameter as the first argument and the
variable name as a string as the second.
This probably seems fairly confusing, so looking at the examples in the Specio::Library::Builtins
code may be helpful.
This parameter is mutually exclusive with the "parameterized_constraint_generator" parameter.
$type->parameterize(...)
This method takes two arguments. The "of" argument should be an object which does the
Specio::Constraint::Role::Interface role, and is required.
The other argument, "declared_at", is optional. If it is not given, then a new Specio::DeclaredAt object
is creating using a call stack depth of 1.
This method returns a new Specio::Constraint::Parameterized object.
