I think this should be considered a bug in the language. I'd expect the tuple
version of foreach to work the same as in any other situation, i.e., allow one
to use an index.

Again, it's only with tuples that foreach with an index works differently. It's
not orthogonal at all to have to use enumerate in one special case.

I'm currently using a workaround, but I think this is a bug. I'd like to get
another opinion on this.
