Imp. Params not subject to defaulting

main = putStr $ show $ foo () with ?x = 13

foo () = ?x

Yields:

    Ambiguous type variable(s) `a' in the constraint
`Show a'
    arising from use of `show' at t2.hs:3
    In the first argument of `($)', namely `show'
    In the second argument of `($)', namely `show $
(foo ())'
