paul Hudak in his 'gentle introduction to haskell" says that a where clause
is allowed only at the top level of a set of equations or case expression.

So you cannot declare
        let
                f x = z / y where z = x + y
        in ....

I do not know the reason why this restriction has been put.
I see the above definition perfectly alright.
Can anybody send me the reason for the above restriction.
