Comment:
The attached patch should fix it. So now for the following code
{{{
module Test where
import Data.Sequence ( (:<) )
import Data.Tree ( Node )
}}}
we get:
{{{
[1 of 1] Compiling Test ( Test.hs, Test.o )
Test.hs:3:24:
In module `Data.Sequence':
`(:<)' is a data constructor of `ViewL'
To import it use
`import Data.Sequence (ViewL ((:<)))'
or
`import Data.Sequence (ViewL (..))'
Test.hs:4:20:
In module `Data.Tree':
`Node' is a data constructor of `Tree'
To import it use
`import Data.Tree (Tree (Node))'
or
`import Data.Tree (Tree (..))'
}}}
