Hi Kip,

A true right to left that parallels interactive J would be:
(%: +/ *:) 3 4
5
Evaluated as follows:
Square the list: 9 16
Sum the list: 25
Square root: 5
With tacit J
1) Three verbs together in parentheses form a fork, so you have
to stop it after two verbs with [:
2) Two verbs together form a hook, so you have to stop the hook
with another [:
([: %: [: +/ *:) 3 4
My point has always been that in simple cases fork/hook grammar is
wordier and more difficult to understand.
That says nothing about complex examples, which I accept will probably
be better expressed in fork/hook grammar. I am hoping to get some examples
that will prove that point.
