[REBOL] Re: Functional programming in REBOL

Hi Ladislav,
Thanks for your many suggestions for a more general cfunc. I will be looking
these over when I get a chance.
BTW I implemented Church numerals last night using cfunc and everything
seems to work ok. Of course, they are not very practical: the Church numeral
100 takes up 235904 bytes!
Meantime, here is another puzzle. Given the definitions from my original
posting:
dupx: cfunc [f2][func [x][f2 :x :x]]
uncurry: cfunc [f][func [x y][do f :x :y]]
Define this function:
puzzle: dupx :uncurry :dupx
What does the function puzzle do?
Cheers
-Larry
