Even though it is undocumented (or poorly documented). I found a cool trick (well a MS dev told me, I didnt really find it)

You can alias project level imports like you can at module level..

So you can do a project level imports like:

SHORTNAME = REALLY.LONG.NAMESPACE.FOR.SOME.DLL

And then SHORTNAME is mapped to REALLY.LONG.NAMESPACE.FOR.SOME.DLL on the project level.

Sort of off topic, but I think its a cool feature...
