On: Ccache – a fast C/C++ compiler cache

Nix is also almost there - it happily uses binaries if they match the exact build inputs but compiles if no binaries match - but it's not nearly as fine grained (you'd need something like 1 package per object file).

And the saddest part is that Nix could be exactly there and solve another one of their problems at the same time: content-addressed outputs.
