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. Thanks, Alexander
