11l benchmark
https://11l-lang.org/ has two benchmarks, one being https://sourceforge.net/p/pqmarkup/code/ci/default/tree/pqmarkup.py which wont be easy to do, the other being primes and only depends on `math.sqrt`, so should be quite easy.

We might be able to bring https://github.com/11l-lang/python_to_11l into the fold.
