You can't have faster compile times. If you want fast compile times C++ needs to sacrifice something else (ABI compatibility, compatibility to compile code from 1979 for some dead big endian 12-bit word chip, etc. In fact the truth is the people working on C++ don't actually value fast compile times over other matters (fast runtime, ABI compatibility, etc.) They say they do. But they don't in their actions. One egregious example: look at the compilation speeds of clang with release build configs (-O2 or higher, etc.) over the years. It compiles much slower now than it did in 2014 for the same code. The compilation speed is worsening at a much faster rate than the runtime speeds are improving from version to version.
