   Just as compact as APL, although I notice you optimized by using a
range
of 2..x-1 instead of 2..x or 1..x-1.

   How does Wilson's Theorem look in SETL?  Note that I am not knocking
SETL,
I just happen to use APL when working on certain types of problems.  An
appropriate higher level language can a great tool for designing and
documenting algorithms, and SETL and APL overlap domains.  SETL is much
better for set theory, and APL for numerical methods.  In either case,
detailed efficiency is secondary while getting the algorithm right.  For
example, when using PROLOG as a design language, you usually want to
forget about cut points.
