The syntactic sugar could either be produced with cpp macros (see Rich's
libc-testsuite) or avoided at all (see the str.c sample I posted in
June, where the arg_next() approach avoids having to use nested loops
at C source level while achieving the same effect as nested loops would).
Or you could use a reasonable mix of these two.

Anyway, now that Luka went with the Python approach already, I think it
makes sense for Rich to take a look a this stuff and discuss it with
Luka before deciding on what to do next.  I'll have to stay out of this,
focusing on other projects.
