## Abstract This pull request removes the `__workaround_52970` concept. This concept is a workaround for a bug described in #52970, which causes the compiler to trigger ADL on a pointer to an incomplete type in an SFINAE context. This bug is fixed in Clang 14. ## Reference - [[clang] Don't typo-fix an expression in a SFINAE context](https://reviews.llvm.org/D117603) - [[libc++] [ranges] ADL-proof the [range.access] CPOs.](https://reviews.llvm.org/D116239)
