I like the idea, but the example suggests that it invokes external programs for trivial stuff, like comparing a variable to an integer (invokes bc and sed). I would prefer if it compiled to pure bash, and only invoked external programs if explicitly called for. But I guess emulating some feature in pure bash is hellish, that's exactly I don't want to write that manually either though.
