The problem can't be solved technically.  It's a human problem after all
and it's amplified by the experimentalism in this community.  I think
the best we can do is to acknowledge its existence, which places us way
ahead of mainstream programming communities.

We don't pretend that type X in lib-0.1.0 is the same as type X in
lib-0.2.0.  What we need to work on is the ability to actually combine
multiple versions of the same package conveniently, i.e. we shouldn't
view this combination as an error.
