Arg, I did it again.  It's a word coming from logic.  When you say

        ``there exist x such that P(x) holds''

an `t' such that P(t) holds is a witness of the property.  I'll take
whatever word you'd suggest to mean ``something which testifies
something happened''.

:) :) :)  I was sure I tested it though...

OK, will do.  Thanks!

BTW, Pavel, what is your opinion on AS_EXECUTABLE_P vs AS_TEST_X vs etc.
