=head1 NAME
PPI::Token::Cast - A prefix which forces a value into a different context
=head1 INHERITANCE
PPI::Token::Cast
isa PPI::Token
isa PPI::Element
=head1 DESCRIPTION
A "cast" in PPI terms is one of more characters used as a prefix which force
a value into a different class or context.
This includes referencing, dereferencing, and a few other minor cases.
For expressions such as C<@$foo> or C<@{ $foo{bar} }> the C<@> in both cases
represents a cast. In this case, an array dereference.
=head1 METHODS
There are no additional methods beyond those provided by the parent
L<PPI::Token> and L<PPI::Element> classes.
