In general, you shouldn't want to do this, as all Factor words
(besides the one I'm about to show you) need a fixed number of
parameters at compile-time. Macros expand at compile-time, so that's
one way to get around the restriction.
The other way it to use a slow word called with-datastack:
{ 1 2 } [ + ] with-datastack
You can also use smart combinators:
[ 2 1 - 3 ] sum-outputs
This works because the quotation infers at compile-time, and
sum-outputs is a "smart" combinator that expands based on the number
of outputs inferred.
You are trying to do a C varargs function, basically, and just as in
C, most Factor words are not varags.
If you have more details about what you want to program, we could help you!
