Julia's module system is the one part of it I feel confident enough to say is bad. It can't handle several versions of the same package. Is hard (or impossible?) to depend on packages that aren't in the registry and hard to add (controversial) things to the registry. I also find it ugly and hard to use but now I'm getting into opinions so I'll stop.
Kip solves all these problems and works fine alongside Julia's current module system so you can try it out now. I hope that eventually we can replace Julia's module system if people generally agree that it's worth doing. I've created a poll to measure the communities opinion <http://tally.tl/3002Y> and you can change your vote at any time so feel free to say no now but follow the discussion.
