module to inject dynamic data into static data

 A method proxy as provided by the Data::MethodProxy module is an array ref
 describing a class method to call and the arguments to pass to it. The first
 value of the array ref is the scalar $proxy, followed by a package name, then
 a subroutine name which must callable in the package, and a list of any
 subroutine arguments.
 .
  [ '$proxy', 'Foo::Bar', 'baz', 123, 4 ]
 .
 The above is saying, do this:
 .
  Foo::Bar->baz( 123, 4 );
