Range is hardly return-type polymorphic. It always returns the same things, you ...

Ok. Now consider what happens with slices/arrays instead of maps.

  1) for k := range list {}

  2) for k, i := range list {}

In python, the equivalents are:

  1) for x in lst:

  2) for x, y in enumerate(lst):

So are these "the same" ? No.

more accurately it's

  for index := range list {}

and

  for index, value := range list {}

Yes, these 2 version do perform very similarly, you are just ignoring the second return value in the first version, i.e.:

  for index, _ := range list {}
