105,Strange error for list comprehension,erikd,,"
Simple piece of code:

{{{
intList ::  [Int]
intList = [ 1 .. 4 ]

main () = do
    println $ show $ [ x + y | x <- intList, y <- intList]
}}}

results in the error:

{{{
ddc: ERROR
    No instance for Class.Num.Num *506

    No instance for Base.Shape3 *506 *521 *531
}}}
