[libcxx-commits] [PATCH] D91292: [libc++] [P0935] [C++20] Eradicating unnecessarily explicit default constructors from the standard library.

[Marek Kurdej via Phabricator via libcxx-commits]

curdeius added a comment.

@ldionne, 've discussed it with @zoecarver, and we decided that I'll take it over. It might take some time as there are many things to change (and test), but I'll appreciate your feedback.

My doubts:

- is using `make_implicit` really necessary or just `test_convertible` is enough? Using `make_implicit` tests as well that the default parameter is the correct one. It's not always possible (as in `random_device` for instance).
- name and location of `make_implicit`?
- I added as well test for ctors being explicit, and that was not tested before.
