> The last point is especially important if your host operating system is macOS, on which it is a really bad idea to directly install a binary Clang other than the one that comes with Xcode.

Why is this? I mean, I understand why you don't want to install over the system compiler, but having another version of Clang installed side by side shouldn't be an issue, should it?

People had all sort of problems when using Apple unsanctioned Clang binaries (problems when Xcode updates, other software gets confused if you add your new Clang to the system PATH). It is easy to get in trouble, better to avoid the problem.

In theory, yes, you should be able to run a different version of Clang side by side.
