Hi GHC people,

I would like to add a primitive to GHC 5.00.2 of the form:

isWHNF :: a -> Bool

I was able to do (something like) this a while ago in 4.06, but have got stuck trying to do the same with 5.00.2.

One problem is that you didn't call it 'reallyUnsafeIsWHNF#' :-) (or you could give it an IO type, to follow the current trend). Simon
