It's been marked as deprecated for some time, but still needs manual removal as of now: https://gitlab.common-lisp.net/iterate/iterate/-/blob/master... (removing https://gitlab.common-lisp.net/iterate/iterate/-/blob/master... should work, I think).

Still better than the loop abomination, IMO.

I made a loop macro using the C preprocessor, for the Awk language.

I had to rub my own eyes to believe that such a thing is possible.

It comes with over twenty useful clauses. Clauses are programmer-definable.

Clauses can combine in parallel or nested/cross-product iteration.
