Yeah, I probably agree -- but I'm trying to just implement the standard
first; that's hard enough.  My only concern is that lookups aren't free,
but I don't yet have any data to know how un-free, and the new parser
isn't smart about this anyway, so there's probably a lot more win from
other lookup-reducing ideas.

Let's reserve these battles until I can pretend to have something that
works passably.  We might as well fix up V3 at the same time; there's
no reason for it not to be conformant.

Note that the "supporting old code" thing is the reason that the V3 
developers, conscientious folks, are writing wrong code -- the compiler 
hasn't been helpful in spotting the bugs.  So, we want a mode that is 
strict, and that is the mode I'm writing; then we can add, under a flag
(or the absence of -pedantic) whatever other gunk we need.
