+1. This would perfectly fit and improve on my current mode of operation.


I'm not quite sure how to handle name clashes, but I expect we can

I would assume the package, because Cabal is normally all about packages.
You can't specify you want to build a particular executable at the moment,
can you?

Would Cabal in your scheme track dependencies between multiple packages
sharing the same repository? If I have multiple related packages in a single
directory, will "cabal build foo" automatically configure and build all
packages that foo depends on? How will you hide the module files of all
other packages from the compiler while it's building one? I assume you'll
copy all the current module files into a separate directory tree before
compiling?
