don't know about that, apparently 2.1a has it

I have a feeling that in order to make nested scopes workable/acceptable
the byte compiler is being hacked and this has had some unfortunate side
effects. It took me a while to get used to the two level (or three if
you split builtins from globals) scoping rule, but I don't miss Algol
style nesting a lot and I find the explicit lambda stuff a help rather
than a hindrance. I would drop this real soon if I could.
