Wish you could do

  for i := range [3:10] {

I think you could write something using the experimental Rangefunc feature that does that.

You can, which makes me wonder why they added the range-over-int functionality when it could have been a function in the proposed iter package:

   for x := range iter.N(10) { ... }

Better yet, you can name it something like `iter.ZeroTo(10)` and it immediately clears up questions about whether it begins from 0 or 1.

My guess because it really doesn't save that many characters compared to

for i:= 3 ; i<10; i++ {}

I didn't count but it might actually be longer.

range 10 is at least shorter
