Scsh (a Scheme based shell) is probably the most promising example of the shell revisited and done in an established language that I've seen, but there are serious problems with it's implementation. It won't run on x86_64 for starters... S-Expressions should allow you to do anything a shell can do, and with good completion (it'd have to be at least as good as Zsh's) I could see it being usable. Somebody just needs to do it right.
