This is AllegroCL since it might be an implementation thing. Someone on
the team reports loop being four times slower than maphash. I see loop
expands to with-hash-table-iterator, never heard of that one before tho
there she is in CLHS.
wtf?

Never mind. Unable to recreate more than 30% lag, eliminated by
compiling the loop version at the speed setting 3 the vendor uses for
maphash, which I learned when the Franz Holiday Tech-Support and
Water-Skiing Team responded.

I've heard Franz is selling support for their Lisp.
But I guess if you cannot afford it, you'll have to ask cll instead.

You mean for the Express edition? For any other license support is free
and awesome.

I asked both as you can see by now (in a followup I posted).
I posted here because I was wondering if there was something I was
missing about LOOP.
