Although I liked the "battery included" approach of GHC so far, I install
more and more interesting "additional" libraries, and GHC is shipped with
libraries I have never used. A library being shipped with GHC has the aura
of being standardized. However also these standard libraries changed, and
I find the interface of some of them not satisfying. Since I expect that
there will never be a consensus on the definition of "relevance" or even
"right interface" I think that the Hackage approach of atomic libraries is
the best solution for the future. It allows me to import libraries
according to my needs, whereas today the decision is often directed by
"what is standard?". With this solution we wouldn't have had the FiniteMap
break, we could choose more equally between different data structure
collections (say Edison vs. GHC libs), monad libraries, and so on.
