Sadly no; I've put out a number of calls for minimal programs (e.g.
small, fairly free-standing real-world applications) but the response
hasn't been terribly strong. I frankly can't blame people for not
wanting to take the time to strip out dependencies from their working
programs. Joachim and I have previously discussed the possibility of
manually collecting a set of popular Hackage libraries on a regular
basis for use in compiler performance characterization.

Cheers,
