NAME

       Math::Symbolic::Custom::Base - Base class for tree tests and transformations

SYNOPSIS

         # Extending the Math::Symbolic::Custom class:
         package Math::Symbolic::Custom::MyTransformations;
         use Math::Symbolic::Custom::Base;
         BEGIN {*import = \&Math::Symbolic::Custom::Base::aggregate_import}

         our $Aggregate_Export = [qw/apply_transformation1 .../];
         sub apply_transformation1 {
            # ...
         }

DESCRIPTION

       This is a base class for your extensions to the Math::Symbolic::Custom class.

       To extend the class, just use the following template for your custom class:

         package Math::Symbolic::Custom::MyTransformations;

         use Math::Symbolic::Custom::Base;
         BEGIN {*import = \&Math::Symbolic::Custom::Base::aggregate_import}

         our $Aggregate_Export = [...]; # exported subroutines listed here.

         # Now implement the subroutines.
         # Exported subroutine names must start with 'apply_', 'mod_',
         # 'is_', 'test_', 'contains_', or 'to_'

         # ...

         1;

   EXPORT
       Uses a custom exporter implementation to export certain routines from the invoking
       namespace to the Math::Symbolic::Custom namespace.  But... Nevermind.

SUBROUTINES

   aggregate_import
       aggregate_import() is the only public subroutine defined by Math::Symbolic::Custom::Base
       and should only be called in BEGIN blocks like the one shown in the SYNOPSIS above.
