Heh?  Do you mean to say that "your way" has the downside that it plain
does not work?  I thought you already had it implemented.

Well, there are two questions:
- how best to implement closures, given the current Emacs C code.
- how best to implement closures, assuming we get to change the C code.

I'm talking about the first question.  Miles's work is within the context
of the second.
