=head1 NAME

PPI::Token::DashedWord - A dashed bareword token

=head1 INHERITANCE

  PPI::Token::DashedWord
  isa PPI::Token
      isa PPI::Element

=head1 DESCRIPTION

The "dashed bareword" token represents literal values like C<-foo>.

NOTE: this class is currently unused.  All tokens that should be
PPI::Token::DashedWords are just normal PPI::Token::Word instead.
That actually makes sense, since there really is nothing special about
this class except that dashed words cannot be subroutine names or
keywords.  As such, this class may be removed from PPI in the future.

=head1 METHODS

=cut

use strict;
use PPI::Token ();

our $VERSION = '1.270'; # VERSION

our @ISA = "PPI::Token";

=pod

=head2 literal

Returns the value of the dashed word as a string.  This differs from
C<content> because C<-Foo'Bar> expands to C<-Foo::Bar>.

=cut

*literal = *PPI::Token::Word::literal;
