This class implements the same API as Specio::Constraint::Simple, with a few additions.

## [Specio::Constraint::Parameterized->new(...)](#Specio::Constraint::Parameterized)

This class's constructor accepts two additional parameters:

- parent
  
  This should be the Specio::Constraint::Parameterizable object from which this object was created.
  
  This parameter is required.
- parameter
  
  This is the type parameter for the parameterized type. This must be an object which does the Specio::Constraint::Role::Interface role.
  
  This parameter is required.

## [$type->parameter](#$type)
