Actually, the word local is bound to the function as well.
/local is just another refinement - it's just treated in a
special way by the help function. The evaluator doesn't
treat it in a special way. You can preset locals like this:
>> f: func [a /local b] [add a any [b 1]]
>> f/local 1 3
== 4
I don't know about you, but I found this quite amusing. All
those earnest REBOL programmers thinking /local is special,
when it's really just a quick, elegant hack.
I love this language :-)
