Yup. It does work. I've used this package for some time.

Well, considering there are dozens of wajig commands, most of which
could be defined by a similar definition body, it would be too crazy to
`defun' them one by one...

The problem here is how to map a macro to a list, which i've been
thinking about all the time. Seems i'm forced to use an explicit
`eval'. Things is a bit different in scsh, though. In scsh, i don't
need that explicit `eval', e.g.,

    (map (lambda (cmd) (run (,cmd))) '(ls pwd))

This works quite nicely, simply wrapping around a macro(run, here) with
a lambda function.
