SH_Overlap6.hs:15:8: error: [GHC-36705]
• Unsafe overlapping instances for C [Int]
arising from a use of ‘f’
The matching instance is:
instance [overlap ok] [safe] C [Int]
-- Defined at SH_Overlap6_A.hs:12:3
It is compiled in a Safe module and as such can only
overlap instances from the same module, however it
overlaps the following instances from different modules:
instance [safe] C [a] -- Defined at SH_Overlap6.hs:11:10
• In the expression: f ([1, 2, 3, 4] :: [Int])
In an equation for ‘test’: test = f ([1, 2, 3, 4] :: [Int])
