"Ambiguos occurrence" error message uses strange qualification
The following text produces an error message that I find somewhat confusing. This issue is just about the wording of the message.
module A (null) where { }
module B where { import qualified A ; null = 42 ; main = null }
when I load B
in ghci, I get
B.hs:1:58: error:
Ambiguous occurrence ‘null’
It could refer to either ‘A.null’,
imported from ‘Prelude’ at B.hs:1:8
(and originally defined in ‘Data.Foldable’)
or ‘B.null’, defined at B.hs:1:39
I think ".. could refer to A.null" looks strange.
I would expect Prelude.null
here, which I do get when I remove "import qualified A" from the text of B
.
