Cleaning one package on a multi-package project

[jcpetruzza]

In multi-package projects, stack clean will clean every package, but I couldn't find a way of limiting this to only a single package (or a subset of packages). Is it possible at all? (when re-building all the packages in the project takes time, this can become annoying rather fast!)

In case anyone wonders, neither cabal clean nor runhaskell Setup.hs clean will do the trick...

Not presently possible but it should be.

What should the usage look like?

Just stack clean pkg and stack clean path-to-pkg?

Or a larger subset of build's target syntax?

I'd say just specifying the package would make sense. It should probably follow similar logic as stack build for selecting the default packages to clean based on the current directory, though.
