Comment (by ezyang):
With the fix, three test cases see a diff like the following:
{{{
-Q.hs:3:8:
- Could not find module ‘Data.Set’
- It is a member of the hidden package
‘containers-@containers-’.
+Q.hs:3:1:
+ Failed to load interface for ‘Data.Set’
+ It is a member of the hidden package ‘containers-’.
Perhaps you need to add ‘containers’ to the build-depends in your
.cabal file.
Use -v to see a list of the files searched for.
}}}
Arguably, "Could not find module" is a better error message; however, this
is indeed the message `-c` gives when it can't find the module, so surely
it can't be that bad?
