DESCRIPTION
This class represents the base of the class hierarchy for tokens in the PPIx::Regexp package.

METHODS
This class provides the following public methods. Methods not documented here are private, and unsupported in the sense that the author reserves the right to change or remove them without notice.

  can_be_quantified
 $token->can_be_quantified()
     and print "This token can be quantified.\n";

This method returns true if the token can be quantified.

  is_quantifier
 $token->is_quantifier()
     and print "This token is a quantifier.\n";

This method returns true if the token is a quantifier. You can not tell this from the token's class, because a right curly bracket may represent a quantifier for the purposes of figuring out whether a greediness token is possible.
