[REBOL] Re: repost [bind example]

Hi Pat,
it is good to have simple and correct examples of BIND usage.
Your example surely *is* correct. It has got only one disadvantage: it is
fairly simple to do that without BIND, if we e.g. use the way Gabriele
promotes:
fn-calculate: function [
nb1 [decimal!]
nb2 [decimal!]
nb3 [decimal!]
cb [block!]
] [f] [
f: func [nb1 nb2 nb3] cb
f nb1 nb2 nb3
]
Your example surely has a didactical value and you can use it. Nevertheless,
it may be useful to show the readers, that this "workaround" is possible as
well. Moreover, Gabriele's "functional" approach looks safer sometimes (and
more natural, at least for some users).
When you posted your example, I tried to suggest a simple example, where
BIND would be better, than a "functional" solution. Initially I considered
my CFOR or SFUN implementation, but, unfortunately, I found out, that they
didn't use BIND at all!
Best regards
