What you are trying to do has serious conceptual problems for reasons I tried to explain in RE (3): BrainPain-Help.

However instead of saying what it is you want to do, why don't you explain what it is that you are trying to do? Then instead of trying to fight the design of the language we might be able to tell you how to get it done working with the language.

For instance you could always pass the variables you want access to in as arguments to the function. Or if it is more convenient, pass in references to the variables instead. (Not strictly needed, but it tends to warn the caller that you may intend to do stuff to the variable.)

I am trying to figure out what you need direct access to your caller's lexical variables for or why providing that wouldn't ruin the entire point of having them - and I am failing...
