That's what it's *for*, surely?
The wheel cache maps (name, version) -> wheel. If I hand you a source directory, you may not even be able to determine the (name, version) except via building a wheel (depending on the resolution to that other thread about egg_info/dist-info commands). And it's certainly not true in general that you can trust the (name, version) from a working directory to indicating anything meaningful -- e.g. every commit to pip mainline right now creates a new different "pip 8.0.0.dev0". So what would you even use for your cache key? I don't see how wheel caching can really help here. -n -- Nathaniel J.
