Template::Plugin::Procedural is a base class for Template Toolkit
plugins that causes defined subroutines to be called directly rather
than as a method. Essentially this means that subroutines will not
receive the class name or object as its first argument.
This is most useful when creating plugins for modules that normally
work by exporting subroutines that do not expect such additional
Despite the fact that subroutines will not be called in an OO manner,
inheritance still function as normal. A class that uses
Template::Plugin::Procedural can be subclassed and both subroutines
defined in the subclass and subroutines defined in the original class
will be available to the Template Toolkit and will be called without
the class/object argument.
