Which is being designed. Maybe that is what you looking for. Also Why not just use gnu make? It has the ability to handle automatic dependence generation for headers already and is how gcc handles its own build system without having to record every new header that is included. > Why this matters: > - Avoids redundancy and human error > - Makes C++ more tractable and tool-friendly > - Brings it closer to the productivity of Rust/Java without changing the > syntax > > Do you think this direction could benefit the GNU system or help evolve > GCC? > > >
