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.
Immediate thoughts:
-
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.
