Understand that I don't disagree with you. But my point is that 
`foreach(int i; 0 .. arr.length)` *never compiled*, whereas 
`foreach(int i, v; arr)` did compile (without deprecation) at 
some point.

This puts it in the category of "features that were removed", vs 
"features that should be added", and therefore gives a little 
less resistance to (re)allowing it.
