+=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.

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