I was going to mention Haskell as being similar. Lots of custom infix operators. On the one hand, once you know a library's custom operators it can make for very clean code, but it can be tough to read code for a library you don't know. I guess it's mitigated a bit by the fact that a lot of Haskell operators generalize well, so the same symbols tend to be used to do something similar, but it can be abused.
