  * Improvements to the "can't find module" error message (#2980)
  Ignore-this: 2de565e20f68ebdc3865df7391c81437
  If the module was found in multiple hidden packages, we list them all.
  
  Could not find module `Data.Generics':
    it is a member of the hidden package `base-3.0.3.0'
    it is a member of the hidden package `syb'
    Use -v to see a list of the files searched for.

    M ./compiler/main/Finder.lhs -49 +55
