    What circular reference? Could you elaborate? The algorithm goes like this:

    1. skip all space till #!
    2. skip #! and read path for the interpreter
    3. find and split arguments
    4. invoke intepreter with it's path at argv[0], arguments at subsequent
       positions and append path to the script at the end.

    That's it, modulo : and no interpreter path at all in the script as legacy
    which is a special case anyway.
