Good.

I thought that was non-negotiable? :-)

Well, you see:
	1) If I hadn't qualified it, somebody would've said "There's this
	   hybrid APL/Lisp processor that can't longjmp because..."
	2) I imagine the committee cares the *most* about the most common
	   uses, so the point was that they wouldn't leave it out just
	   because some vector processor had trouble with it; it's too
	   valuable for the normal cases. Adding "noalias" (unesthetic
	   though it may be) is not quite the same as deleting a normal,
	   heavily used feature. (Ok, now raise the issue of constant
	   strings :-) But that's not *heavily* used.)

Hmmm. Does this undermine me?
