A while back I wrote a little test snippet[1] to see how good such an interface can get in python.

    _("ls -la") | _(lambda x: x.split()[-1]) | _(lambda x: os.path.splitext(x)[1])

I wonder if there's a complete version of something like this out there. You can probably get pretty far staying in Python-land, plus, everything else is free (data types, standard library, adoption, etc).
