NAME

       Template::Namespace::Constants - Compile time constant folding

SYNOPSIS

	   # easy way to define constants
	   use Template;

	   my $tt = Template->new({
	       CONSTANTS => {
		   pi => 3.14,
		   e  => 2.718,
	       },
	   });

	   # nitty-gritty, hands-dirty way
	   use Template::Namespace::Constants;

	   my $tt = Template->new({
	       NAMESPACE => {
		   constants => Template::Namespace::Constants->new({
		       pi => 3.14,
		       e  => 2.718,
		   },
	       },
	   });

DESCRIPTION

       The "Template::Namespace::Constants" module implements a namespace handler which is plugged into the "Template::Directive" compiler module.
       This then performs compile time constant folding of variables in a particular namespace.

METHODS

   new(\%constants)
       The new() constructor method creates and returns a reference to a new Template::Namespace::Constants object.  This creates an internal
       stash to store the constant variable definitions passed as arguments.

	   my $handler = Template::Namespace::Constants->new({
	       pi => 3.14,
	       e  => 2.718,
	   });

   ident(@ident)
       Method called to resolve a variable identifier into a compiled form.  In this case, the method fetches the corresponding constant value
       from its internal stash and returns it.
