Okay, real quick because I mostly did other stuff today and it's late. I went through the syntactic bestiary from the Syntax Construction Kit some more. Most of the ones I looked over today, I decided to skip for now because I don't have a clear picture of the aesthetics in those areas.
I guess I'm hoping to see something that I can latch onto as interesting, aesthetically pleasing, and distinct from languages that I know.
I should wrap up for now. Next time, I should take inventory of the stuff I more-or-less know how to do, so I know what to focus on next.
