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.
