That would also work; the naming is a bit more awkward, but then you
don't have the issue of mutually-exclusive optional arguments where
exactly one of the two arguments is required.

I'm leaning slightly towards the approach that Benoît took, if only for
the naming aspect (that is, I also thought of the idea of a bool flag,
but didn't suggest it because I didn't like the implications on the
naming).  But I can live with either approach, if anyone else has a
strong opinion.
