I forgot that Clang is a large install. We should assess if it really is needed to recompile quick fixes in the moment.

Do we need a compiler to compile code for quick fixes? Yes.
I am not aware of Clang alternatives. Perhaps you can research in smaller C++ compilers like TinyC (unfortunately, this works for C only) .
Can you tell me how much more time and space does clang require?
