Here's how it's done using wily:

  grep -rn functionName src |grep hs: |grep -v Context.hs

It provides a clickable list!!  :-)

For convenience I have the above command, with extra .svn,
_darcs, etc stuff in an executable sh file (well, it's actually
an rc file, plan9 shell), so I just type:

  grh functionName

Well, actually I usually already have the text grh in a
"tagline" or some guide buffer, so I just click on the
functionName and then click on grh, to get the list, and then
click in the list to get to the right file and line.
