Comment (by Simon Peyton Jones <simonpj@…>):

 In [changeset:"fb7c311711c8851d0de1e40231150ad999ae9c2b/ghc"]:
 {{{

 Repsect the package name when checking for self-import

 Fixes Trac #9997.

 In doing this I tripped across the specialness of "this" in
 PackageImports.  The magic constant (fsLit "this") is scattered across
 the compiler and ought to be put in one place.  But where?
