Sorry in advance if I should be posting questions of this kind elsewhere (please tell me if so!).
Consider this two file program: ``` module T where main = undefined
module Main where import T main = putStrLn "Hello world!" ```
Both 8.4.3 and 8.6.3 agree: ``` Main.hs:1:1: error: Ambiguous occurrence ‘main’ It could refer to either ‘T.main’, imported from ‘T’ at Main.hs:2:1-8 (and originally defined at Main.hs:2:1-4) or ‘Main.main’, defined at Main.hs:5:1 ```
Is this expected behavior? Does it not contradict "If the export list is omitted, all values, types and classes defined in the module are exported, but not those that are imported" ( https://www.haskell.org/onlinereport/haskell2010/haskellch5.html)? If the latter, is this a bug? What am I missing?
The language you cite from the report makes it sound as though this is a bug. Can you open a ticket? Cheers, - Ben
