Which symbolic programming languages do exist?

Question

While there were a few discussions about non-English programming languages here on HN, what about programming languages that rely on symbols instead of natural languages? It appears that APL is one such language, are there any others?

BQN, although that feels like cheating, because it's very much APL-derived: https://mlochbaum.github.io/BQN/
