@CaseyCarter I believe the example in the draft standard might perhaps contain a very minor error.

http://eel.is/c++draft/range.iota#overview-2

Shouldn't the comment be prints: 1 2 3 4 5 6 7 8 9 10 ?

[ Example:

for (int i : iota_view{1, 10})
  cout << i << ' '; // prints: 1 2 3 4 5 6 7 8 9

— end example

Why? See http://eel.is/c++draft/range.iota#sentinel-2 When the value of the iterator is equal to the upper bound (in this case 10), the iterator is equal to the sentinel and thus the loop stops.

As @Rakete1111 says, the arguments to view::iota are treated as a half-open interval [first, last).
