Both GHC and Hugs have a bug in their Prelude for Ratio's Enum
instance. The following program
import Ratio
main = print [ 1, 4%(3::Int) .. 2 ]
should print
[1 % 1,4 % 3,5 % 3,2 % 1]
but instead an infinite list of 1%1s is generated. The reason for this
is that the default method for enumFromThenTo is used, which truncates
4%3 to 1 (same for enumFromTo).
Cheers,
Sven
