Er, actually I'm all _for_ fixing partial functions. Some things like
head/tail will be contentious to get rid of ---and aren't my main concern
ATM---, but the partiality in the Enum class (for example) is flagrantly
unnecessary.

It's just the other two (numeric hierarchy, MPTCs/fundeps/TFs) I think
would best be handled elsewhere/later.

I wrote a preliminary version of this at:

    http://www.haskell.org/pipermail/libraries/2013-May/020046.html

cf also:

    http://www.haskell.org/pipermail/libraries/2013-May/020049.html

A handful of the proposed changes are covered by the Applicative => Monad
proposal, though that proposal is more aimed towards retaining
compatibility rather than ironing out all the wrinkles.

Before writing up a more detailed version of 020046, I'd like to get
feedback on whether there are particular warts I missed or particular
suggested changes that people are stringently opposed to (once concerns
about compatibility have been put aside).
