Issue: HASH-TABLE-ACCESS (version 1)

[Kent M Pitman <KMP@STONY-BROOK.SCRC.Symbolics.COM>]

I'll support this, though I would -really- like to see this business of
the test (EQ vs #'EQ) resolved.

Personally, I feel that since the set is non-extensible, we ought to
change it to allow only :EQ, :EQL, or :EQUAL (and permit implementations
to accept other values for compatibility). Then the value returned
by HASH-TABLE-TEST could be deterministically :EQ (or whatever) and
we could do away with the popular Trivial Pursuit (TM) question about
how the test is recognized. I think it would simplify a lot of things.
If people buy this, I will write it up as a separate cleanup item.
