=head1 NAME

MooseX::Declare::Context::Parameterized - context for parsing optionally parameterized statements

=head1 VERSION

version 0.40

=head1 DESCRIPTION

This context trait will add optional parameterization functionality to the
context.

=head1 ATTRIBUTES

=head2 parameter_signature

This will be set when the C<strip_parameter_signature> method is called and it
was able to extract a list of parameterisations.

=head1 METHODS

=head2 has_parameter_signature

Predicate method for the C<parameter_signature> attribute.

=head2 add_parameter

Allows storing parameters extracted from C<parameter_signature> to be used
later on.

=head2 get_parameters

Returns all previously added parameters.

=head2 strip_parameter_signature

  Maybe[Str] Object->strip_parameter_signature()

This method is intended to parse the main namespace of a namespaced keyword.
It will use L<Devel::Declare::Context::Simple>s C<strip_word> method and store
the result in the L</namespace> attribute if true.
