I'm only inquiring about changing the clean hook for this specific project, 
not cabal in general.

And the reason I'm looking to change it is that building the C++ component 
takes a long time (over five minutes on my fairly average laptop), so 
cleaning everything every time is an extremely annoying inconvenience.

My main questions are:
1. Is there some reason (other than 'safety') that "cabal install" cleans 
everything up?
2. Why does setting cleanHook to return () not have any effect?

Thanks,
