I am working on a design for one as well. It's rather tricky, because there are a lot of things you have to balance in order to get a well-designed programming language, especially when you want it to be usable for the sort of things shell scripting is good at, because shell as it exists is basically the opposite of a well-designed programming language and is only popular because it got here first.
