I've always understood the 58 in Algol 58 to indicate the year of its origin, which would be a couple years after IPL, but I'm no historian. The bit of checking I've done suggests this is correct.

Hi Chris
Further nigling point -- did not ALGOL with recursion precede IPL? ALGOL also had array bound checking -- think of all the buffer overflow attacks that could have been prevented!

Niggling historical point: IPL had recursion a couple of years before LISP.
