Nickle is a programming language that a bunch of the people working on X seem fond of. I haven't really read enough about it to evaluate it, but it looks somewhat interesting: rather C-like, but with more type safety, garbage collection, first-class continuations, etc.

The twixt control statement is a more clear way of expressing a concept usually expressed with a try...finally–type expression. Ruby (and I assume Smalltalk) use some interesting patterns with blocks: for example, mutex.synchronize takes a block (read: anonymous function) and does the lock/unlock around it; File.open does a similar thing with opening and closing a file. But those are usually implemented in an ad-hoc manner.
