Defect reports
The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
| DR | Applied to | Behavior as published | Correct behavior |
|---|---|---|---|
| LWG 3714 (P2711R1) |
C++20 | the multi-parameter constructor was not explicit | made explicit |
| P2325R3 | C++20 | if Pred is not default_initializable, the default constructorconstructs a take_while_view which does not contain an Pred

the take_while_view is alsonot default_initializable
