Yes.

It should give an error - 5 is not a sequence, so 'i in 5' is nonsense.

If you really want to change that, making it equivalent to for i in [5]:
seems the most natural meaning to me.

For iterating over the values 0..4, we have the nicely explicit and Pythonic
for i in range(5):. I haven't seen one very good reason why we need a second
way to do that - saving a few characters surely isn't enough.
