No, there's no reason it's not exported, excepting only that it's not currently called outside TcRnDriver. Go ahead and create a ticket and patch. It should be exported from GHC.hs (ie the official GHC API), not merely from TcRnDriver. And I suggest you add a comment with the export from GHC.hs to explain why it's exported. Otherwise someone might delete it again!

If not, can it please be added? (I considered sending a patch with this email, but it's so trivial a change that the check of the patch is more work than manually adding runTcInteractive to the export list.) I'm developing against the GHC API of 7.6.3 and it would have saved me hours of work to have precisely that function. Seeing it's in HEAD, but not being exported seems a shame ;) Regards, Philip
