Comment (by Edward Z. Yang <ezyang@…>):

 In [changeset:"1bd1ceffce7f3027ae632086844f95976ed600c8/ghc"]:
 {{{
 #!CommitTicketReference repository="ghc"
 revision="1bd1ceffce7f3027ae632086844f95976ed600c8"
 Don't use self {-# SOURCE #-} import in test-cases.

 Summary:
 It's kind of buggy, c.f. #10182, and isn't motivated by any
 real world programs, so we're going to get rid of it (despite
 it being handy for GHC test cases.)
