Eta-reduced term has wrongly inferred monomorphic type
Hi,
When creating a file with the following two definitions:
rowtotals xs = map sum xs
rowtotals' = map sum
And loading this file in GHCi. Asking for the type of the two definitions gives:
*Main> :t rowtotals
rowtotals :: Num b => [[b]] -> [b]
*Main> :t rowtotals'
rowtotals' :: [[Integer]] -> [Integer]
Is this the expected behaviour? I would expect both to have the same polymorphic type.
Cheers, Christiaan
