The reason I'm proposing this is consistency: the idea behind the two
Library folders is that your Haskell installation is the union of the
/Library/Haskell and the ~/Library/Haskell directories. The only
difference between these two directories should be that the former is
available to all users while the latter is available to just a single user.

On a related note, with the


layout for packages in place, it would ideally be possible to  mv
packages from /Library to ~/Library and vice-versa, making them
available to all users or to just a single user with a simple file
rename. At least, that's the OS X philosophy. Our main obstacle would be
to figure out what to do with dependents and dependencies.
