Hello,
1.
I have curried (compose) so that I can define (not2) below,
(define compose(lambda(f)
(lambda(g)
(lambda(x)
(f(g x))))))
(define not2
(compose not)
)
((not2 null?)'())
This is OK.
2.
I do this also,
(define both(lambda(f)
(lambda(a b)
(and(f a)(f b))
)
))
(define neithernull
(both ((compose not)null?) )
)
(neither '()'())
This is OK.
3.
But both here below are ERR,
(define neither
(both ((compose not)) )
(define neither
(both (compose not))
The first one doesn't compile. The second one does, but this is not what I
meant; It suspects two arguments, the '() '() for example , instead of one,
the funtion null? for example.
Can I define (neither) is some way that I can do something like
((neither null?)'(a)'(a))
Thanks,
Eric J.
