NAME

       PPIx::Regexp::Util - Utility functions for PPIx::Regexp;

SYNOPSIS

        use PPIx::Regexp::Util qw{ __instance };
            .
            .
            .
        __instance( $foo, 'Bar' )
            or die '$foo is not a Bar';

DESCRIPTION

       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.

SUBROUTINES

       This module can export the following subroutines:

   __instance
        __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.

   __is_ppi_regexp_element
        __is_ppi_regexp_element( $elem )
          and print "$elem is a regexp of some sort\n";

       This subroutine takes as its argument a PPI::Element. It returns a true value if the
       argument represents a regular expression of some sort, and a false value otherwise.

   __ns_can
       This method is analogous to "can()", but returns a reference to the code only if it is
       actually implemented by the invoking name space.

   __to_ordinal_en
       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

SEE ALSO

       Params::Util, which I recommend, but in the case of "PPIx::Regexp" I did not want to
       introduce a dependency on an XS module when all I really wanted was the function of that
       module's "_INSTANCE()" subroutine.

SUPPORT

       Support is by the author. Please file bug reports at <http://rt.cpan.org>, or in
       electronic mail to the author.
