Tie::Expression - Let any %hash interpolate any expression.

$Id: Expression.pm,v 0.1 2008/07/01 17:56:27 dankogai Exp dankogai $

  use Tie::Expression;
  tie my %expression, 'Tie::Expression';
  print "PI = $expression{ 4 * atan2(1,1) }.\n";

This module makes any tied hash a universal interpolator. Just feed its key any expression and the result of the expression becomes the value.

It is known that @{[ expression ]} is a univasal interpolator but the solution with this module is more elegant.

The implementation is deceptively simple. Just check the source and you will find this module is just six lines long!

Percent::Underscore

Nothing.
