I suppose I am changing the subject, but this reminded me of the
Mortran2 processor, and also I believe the code it generates, which
has a comment something like:

C This code is meant to be understood by machines and not humans.

Paraphrasing because I haven't seen it for many years. I did a google
search for it, but still haven't found an actual copy, though I did
find Mortran3.

The Mortran series are processors for a Fortran-like language, that
generate Fortran code. It is pretty much a macro processor and a set
of macros, though much of the work is done by macros that modify other

It is an interesting example of some of the ideas for programming
languages in the 1970's.

Little known fact: early versions of yacc could produce a parser in
Fortran, so ratfor used a yacc parser. -John]
