Numeric literal printed wrong in error message
Compile the following with -Wall
default (T)
data T = T deriving (Eq, Ord, Read, Show)
instance Num T
instance Fractional T
main = interact $ show . (< 1e400) . readThe error message says
Bug.hs:7:28:
Warning: Defaulting the following constraint(s) to type `T'
`Fractional b'
arising from the literal `Infinity' at Bug.hs:7:28-32There is no literal Infinity in my program, I wrote 1e400, which could be a perfectly good literal for the type T. I don't wanted printed as Infinity.
