This reminds me of a very handy feature in ipython (a custom python
repl) - you can type


which prints the docstring associated with name (which can be a
function, module, class etc.) - but if you type


you get the docstring _and_ the source code (colorized and all :). I
use it a lot when I'm experimenting in a interactive session. I could
see something similar for haskell being very useful, to me at least.
