There are a lot of programming languages that aren't very well-known now, but may have some interesting features. I keep finding a new one every now and then.
They may have faded to obscurity, they may still be in development, they may serve a small niche, or they may just not have caught on.
Do you know any? Any language that is not too popular and has at least one cool feature is welcome!
I consider these languages to be 'established', but if you have a useful-but-obscure feature, that's welcome:
