In general you can't do this whether you use pats of QuickCheck or not
- `randomEvalute` would need to inspect the supplied function to see
how many input parameters it has so it can list them, but there is no
such introspection in Haskell.

Yes - I was just checking the first QuickCheck paper to see how the
authors did this.
You would need a new type class that works like `Testable` and the
versions of associated machinery `forAll` and `evaluate` to unroll
function application.

I have a working code of this but for that I have to reimplement Arbitrary
and Testable typeclasses which I don't want to do. I thought it might be
possible to use parts of quickcheck without actually changing its code but
still I am unable to find a suitable solution.

I think it's more complicated because he doesn't know what the return type
or arity of the function is. In QuickCheck they know the return type of a
property is Bool. In this case, we only know that the return type is an
instance of Show. I don't think that's enough to simply implement this.

I am trying to use quickcheck to generate random arguments of a given
function (assuming all its types have Arbitrary instance and Show instance)
along with the evaluation of the function at those arguments.
Suppose I have a function
add :: Int - Int - Int
add a b = a+b
Then I assume a
