I think that this solution was already discussed. It has the drawback that
I can no longer be sure what's actually in an installed package. If I have
the package dependency foobar=1.0 in my Cabal file then I must be sure
that foobar-1.0 on every user machine will contain all the modules in the
same state as I have installed on my machine.


If Cabal packages are mapped 1:1 to Debian or RPM packages then it would
be really cumbersome to have to split up a project to one Cabal package
per executable.  Otherwise it's ok for me to handle executables in
separate units ("sub-packages" or just "packages").
