Do you have an example? That is meaningful I mean.

Although nothing is stopping you anyway from using the same index variable,
because they are all the same variable, it's going to cause difficulties, so
it doesn't happen.

But with mixed declarations it will work, because all the 'i's are distinct.
However, it's just confusing

(What *is* a good idea, I think, is to just auto-declare for-loop variables
anyway. Then the question of where to declare them is eliminated!)

And if a function is short, there's less to gain from localising all the
declarations.
