This module contains utility functions for PPIx::Regexp which it is convenient to centralize.

The contents of this module are private to the PPIx::Regexp package. This documentation is provided for the author's convenience only. Anything in this module is subject to change without notice. Caveat user.

This module exports nothing by default.


This module can export the following subroutines:


 __instance( $foo, 'Bar' )
     and print '$foo isa Bar', "\n";

This subroutine returns true if its first argument is an instance of the class specified by its second argument. Unlike "UNIVERSAL::isa", the result is always false unless the first argument is a reference.


This subroutine takes as its argument an integer and returns a string representing its ordinal in English. For example

 say __to_ordinal_en( 17 );
 # 17th
