I’ve been playing with modules-enabled builds a bit and would like to raise some awareness of this seemingly underrated feature. To my knowledge it’s mostly associated with/used/maintained on Mac with libc++.
But it works fine on Linux too and even with libstdc++ when using a proper modulemap (I tuned one from swift).
The build time savings for a release clang build are significant (OFF vs ON results, the tool is CompileScore):
