I agree with [?Skip?] that the file's *name* is a poor way to determine
whether magic behavior should be invoked.

Seems to me that the interpreter should know it's own length as an
executable. Then, if it gets loaded from a longer file, it can assume
there are zipped modules to be imported and run by whatever mechanism is
decided. Quite how to implement this without an extra pass is beyond me.
