I'm quite familiar with Scheme and can do useful things with it. Not so sure how comfortable it would be to have Scheme on the command line. Maybe it's just a matter of getting used to s-expr in that context, but after a few decades learning the classic command-line syntax, making that change could be hard. OTOH the ability to use low level OS functions at the shell prompt or in a script might compensate for the trouble. Giving it a try would be the only way to find out. I might just do that and see what happens.
