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.
