In my case (emacs 24),  the enter key feeds the line to the
interpreter. ghc-mod with flymake is great but it seems not to work
for problems related to type checking. I selected ghc instead of hlint
but only syntax errors are highlighted.

I think it would be very efficient to load the buffer into the
interpreter and then navigate through the errors without ever living
the buffer and with minimal effort. Currently I need to spot the line
number reported in the interpreter buffer and then jump to that line.
