API for looking-up/retrieving Haddock comments?

Hello, I've been wondering if there have been attempts to provide some library/API or similiar facility (other than pointing your web-browser to the static Haddock HTML report) for looking up Haddock comments associated with Haskell symbols? As an obvious application: When coding in dynamic languages (e.g. Python, Elisp, or GNU R to name a few), I've learned to appreciate the ability to lookup up documentation interactively from the tab-completing REPL w/o having to "switch context/focus" to different application (as I currently do: I have to switch from GHCi to a web-browser and first locate the appropriate package/module and then find the symbol I'm interested in). cheers, hvr
