What Hacker News says
5 sourcesThat Structured Haskell Mode (https://github.com/chrisdone/structured-haskell-mode) readme has some very interesting gifs to show how things work.
It's pretty powerful, and I use SHM in my Haskell stuff to mostly good effect. I just have some issues involving the default indentation that I need to get round to fixing, and I haven't figured out how to surround a block with square brackets yet. But otherwise, very good stuff.
In Prune: A Tree-Based, Home-Row-Oriented Code EditorAn interesting idea that's definitely worth exploring.
However, I think the conflict between tree-based editing and normal editors is completely unnecessary. In fact, you can actually get basic tree-based editing today in Emacs!
The easiest language to support like this is Lisp because its syntax is about as close to pure tree as possible. And, indeed, Emacs has had structural editing for lisp for a while in the form of Paredit[1]. More recently, somebody extended this idea to Haskell[2] which is interesting because Haskell has one of the more complex, persnickety syntaxes around.
I'm not saying either of these are as good as dedicated editors—I'm not even convinced they could be as good—but they are low-cost ways to try these ideas out right now without abandoning general-purpose text editing or creating a brand new tool.

Their IDE is web only, though they just open sourced a good portion of it. I have found that most people use vim or emacs. If you are trying to decide, I'd pick emacs, as Chris Done has written some nice scripts (https://github.com/chrisdone/structured-haskell-mode). Personally I use vim. Also check out ghc-mod and hdevtools.
In School of Haskell 2.0There are all sorts of tools, even for refactoring. Maybe not to the degree of Java, no. Although, haskell code tends to have less boilerplate, so there is less toolig for manipulating boilerplate. (Not to say there are other tools that could be improved). But the situation is far from dire.
-- Vim:
haskellmode-vim for show type and insert type, among other things.
ghcmod-vim for HLint and HCheck, also used by Syntastic and NeoComplCache.
neco-ghc uses ghcmod-vim for nifty Haskell completion, powered by neocomplcache.
Syntastic automatic syntax checking for vim.
