Really when you think of it, anyone asking if 0 is a prime number deserves all they get. :-)
@ Henry -could we have a stdlib verb (or a new Foreign) to verify the integrity of all cached numeric nouns? Maybe even reinstate them, to save having to restart J repeatedly? Or just tell us where they're listed, in either jsource or the test suite. I knew i.n was cached for low values of n, but not 0.
