I remember being really interested a few years ago when it was billed as a superset of Python. I know they pivoted away from that, but I might play with it now that the compiler is also open source.
So far I've been enjoying the language (pythonic, comptime, tile support) and plan to spend time using it to work with gpus to learn more, the puzzles are also pretty cool.
