For the giggles:

nice idea, but "small composable programs" includes perl scripts? That's great if you're already using perl, a bit much to install if you're not.

There shouldn't be any burden of portability for the one writing small tools like these. You're free to rewrite it, of course, but expecting someone to go out of their way to stay within the unix/posix/whatever environment seems a bit much given the context of an unpaid endeavor.
