2636,Error message for missing import substantially worse in 6.9/6.11,NeilMitchell,igloo,"Creating a file Test.hs:

{{{
import Foo
main = print ""hello""
}}}

where Foo does not exist, used to give a really nice error (with 6.8.3) but with 6.9 and 6.11 gives a horrible error message:

{{{
$ runghc Test
*** Exception: Could not find module `Foo':
  Use -v to see a list of the files searched for.
$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 6.11.20080929
}}}

Compared to version 6.8.3:

{{{
$ runghc Test.hs

Test.hs:2:7:
    Could not find module `Foo':
      Use -v to see a list of the files searched for.
}}}

A much nicer error, importantly saying where the import was - in my case the import was in an imported module, so I didn't even know which file was causing the error.",merge,closed,high,6.10.1,Compiler,6.9,fixed,,,Unknown/Multiple,Unknown/Multiple,,Unknown,,,,
