Hi John,
I think Jeff's example (subject: [REBOL] Functional programming in REBOL Re:):
use [pod][
do pod: func [x][
any [all [zero? x 1] all [odd? x x * pod x - 1] pod x - 1]
] 20
]
which, when executed evaluates to:
>> use [pod][
[ do pod: func [x][
[ any [all [zero? x 1] all [odd? x x * pod x - 1] pod x - 1]
[ ] 20
[ ]
== 654729075
actually demonstrates that "it is possible to write mostly functional
code that can handle reasonable amounts of data".
