Comment (by nomeata):

 Shoudn’t you use the GHC API then? Parsing output meant for human
 consumption has a certain smell of abuse.

 It would be great if one can run arbitrary `GhciMonad` actions from the
 interpreter prompt. Dennis Felsing has started some work in that
 direction, see http://www.haskell.org/pipermail/glasgow-haskell-
 users/2012-December/023161.html for pointers.
