I think EclipseFP gives you this. (I can't remember if it supports section
folds, Haskell is sufficiently terse that I've never needed it :-)

According to a few articles I've read, cabal dependency hell is caused by
installing packages with -o, which inlines code from dependant packages.
Why isn't this avoided by installing packages without inlining? Packages
could still be recompiled with -o in a cabal-dev sandbox, but the package
repository would be free of dependency hell.

-O, not -o.

Because the performance is somewhere between horrible and abysmal.

Every OO language which supports generics allows a declaration such as
List<Show> alist, where Show is an interface. Any type implementing Show can
be put in alist, and any Show operation can be performed on the alist's
members. No casts, wrappers, or other special types and plumbing are needed.
Why isn't it possible to do this directly in Haskell?

Thank you, does this mean that dynamic linking wouldn't work either?

Just to make sure... I guess you've already read
http://www.haskell.org/haskellwiki/Heterogenous_collections right?
