RE: [sv-ec] foreach iterates over unpacked arrays

The argument about arrays of arrays versus multi-dimensional arrays does
not belong here.

What I was trying to clarify is what's difference between an "empty
variable" versus an "omitted variable" and when commas are required as
placeholders.

I'm just going to ignore that issue in the proposal since it seems to be
ignored everywhere else.
