Good news, everyone!

But if multiple versions of the same library can be linked into one
binary, then the binary sizes will increase and therefore the memory
usage might increase and even performance might decrease a bit if
the number of cache misses increase.
This is not in the current proposal. GHC knows how

Hi Simon,
It is tantalising to me that something so critical has been so long delayed.
It’d be fantastic if it was done this summer.
I'm just wondering what kind of negative side effects it might have.
Sure, it will - most likely - make installing of cabal packages a lot
easier, especially

As I think Simon was saying earlier, think of this feature as allowing
strictly more installation plans to succeed, while still keeping to the
exact same model that we use today of just one instance of a lib in any
given binary.
Currently, if you install B-0.1 and then install A-2.0 that has a
