There are newer versions of M/MUMPS around and some of them are open-source such as YottaDB https://yottadb.com/ and Reference Standard M https://gitlab.com/Reference-Standard-M/rsm .

I've never been quite brave enough to try to build something with it.

The project is intentionally about the MUMPS 76 standard and its anniversary, see https://github.com/rochus-keller/MUMPS/blob/main/Readme.md.

Agreed, I just wanted to point out that it is still around!
