Perl module for specifying method calls in a static configuration

 The method proxy concept provided by the Config::MethodProxy module is
 a particular data structure which, when found, is replaced by the value
 returned by calling that method. In this way static configuration can be
 setup to call your code and return dynamic contents. This makes static
 configuration much more powerful, and provides the ability to be more
 declarative in how dynamic values make it into the configuration.
