I find myself writing

What about relaxing the syntax to allow

     foreach (; 0 .. n)

and/or

     foreach (0 .. n)

?

Thereby making the `ForeachTypeList` of `AggregateForeach` in the grammar rule [1] optional.

Meh, is this a common need though? The first form isn't terrible.

In general, I'd say it would be nice to designate _ as an unused variable (i.e. not allowed to access it, and it doesn't trigger shadowing errors). It's like this in Swift for instance.
