ghci should show haddock comments for identifier
This came up in comp.lang.haskell recently: http://groups.google.com/group/comp.lang.haskell/msg/ae69f720377e7a3f
I like the idea.
if ghci reads the source file, it can read haddock annotations
if ghci reads the interface file only (for library modules),
it needs to find the installed documentation
On the other hand the requested feature is a typical IDE functionality (cf. Eclipse/show source/show javadoc) and it's perhaps a bit much to require that from ghci.
