Re: merge wip-haskell?

Hi Jakub,

I could see splitting the static output being useful but I would rather wait 
until some evidence that the closure size would be too large. Also I’m not sure 
propagation is necessary for dependents to find libraries or use paths from an 
input.

Thoughts?

Perhaps we should work on making propagated-inputs per-output? That way,
:static could propagate the :static output of the dependencies.

This would also be useful in other situations. For example, a package
might contain both a binary and a library, and the library must
propagate its dependencies to make the header files work.

I don't know what a good syntax for this would be.

Thoughts?
