URL: https://github.com/llvm/llvm-project/commit/dc78a5281539056dba23c823576a70d2661ad972 DIFF: https://github.com/llvm/llvm-project/commit/dc78a5281539056dba23c823576a70d2661ad972.diff LOG: [clang][NFC] Mark CWG1336 as implemented and add a test (#196000) [CWG1336](https://wg21.link/cwg1336) clarifies that, as long as it isn't explicit, a constructor is still a converting constructor even if it has multiple arguments. Clang seems to implement this since 3.1: https://godbolt.org/z/919zdMd3h (I checked a few versions following 3.1 as well, and didn't notice any regressions).
