SG9 in Hagenberg
SG9 saw this paper in Hagenberg. As a result of discussion of P3555R0, we discovered that [iterator.requirements.general]/10 implies code like views::iota(0) | views::take(3) is undefined behavior.
We took the following poll:
We agree that this needs correcting:
| SF | F | N | A | SA |
|---|---|---|---|---|
| 9 | 4 | 1 | 0 | 0 |
Strong consensus
The authors plan to come back with a much more extensive fix to this problem, which is much larger and more widespread than we originally believed.
