+1.  Kill the comma operator with fire.  Usage in for-loops should be
done as special-case syntax, *not* as comma operator (i.e., "," in for
loops should be accepted as part of for-loop statement syntax, not as
part of expression syntax).

What to do with tuple syntax is a different kettle o' fish. But before
we get there, we need to kill comma first. So let's at least take this
first step.
