I was playing with QuickCheck and I just wanted to put
all of my tests in a list, but that's not possible,
because of the fact that a list can only contain
values of the same type.
So concrete I would like to write down this:
prop_RevRev xs = reverse (reverse xs) == xs
where types = xs::[Int]
See http://www.cwi.nl/~ralf/HList
for a paper which shows how to implement a heterogeneous list in haskell, and
how to implement operations on it (amongst other things)...

I didn't expect these replies (including one
mentioning the HList idea(the enforced ordening is
nice, though)), while I tried to be pr
