=head1 NAME
Specio::Constraint::Parameterized - A class which represents parameterized constraints
=head1 VERSION
version 0.33
=head1 SYNOPSIS
my $arrayref = t('ArrayRef');
my $arrayref_of_int = $arrayref->parameterize( of => t('Int') );
my $parent = $arrayref_of_int->parent; # returns ArrayRef
my $parameter = $arrayref_of_int->parameter; # returns Int
=head1 DESCRIPTION
This class implements the API for parameterized types.
=for Pod::Coverage can_be_inlined type_parameter
=head1 API
This class implements the same API as L<Specio::Constraint::Simple>, with a few
additions.
=head2 Specio::Constraint::Parameterized->new(...)
This class's constructor accepts two additional parameters:
=over 4
=item * parent
This should be the L<Specio::Constraint::Parameterizable> object from which this
object was created.
This parameter is required.
=item * parameter
This is the type parameter for the parameterized type. This must be an object
which does the L<Specio::Constraint::Role::Interface> role.
This parameter is required.
=back
=head2 $type->parameter
Returns the type that was passed to the constructor.
