The function name is available to the closure as an upvalue,
so you don't need a global to hold it as well.  (The
zeus_hook function took care of that.)

So now the macro name is at the _top_ of the stack.  You
can use -1 as a stack index to retrieve it:

    String szFunction = lua_tostring(pLuaState, -1);

Make sure to copy the string when you pop it off the stack
as the char* is then invalid (presumably your String type
does this?)
