Good catch. Interestingly, the definition of FIND does not mention
that, and given the return values that FIND can produce, and the way
that FIND is used, I don't think it makes sense. I don't think there
are any Forth systems that produce an error when performing
: c-if c" if" ;
c-if find
Of course, some people find it surprising that
c-if find drop execute
produces an error in Gforth 0.7, but errors produced during execution
of xts returned by FIND are no rarity.
