I have a collection I need to pass to foo after the first arg like this:

(foo "some value" my-collection)

What I need is a way to expand my-collection into individual arguments
that are passed to foo so that they will be collected back into
other-args as a sequence. I could create a new sequence containing
"some value" and the items in my-collection and then use apply on foo
and the new sequence. Is there a better way?

        (apply foo "some value" my-collection)

Here's a concrete example:

        user=> (apply + 3 4 [5 6 7])
        25

--Steve

Apply takes any number of individual elements before the final collection:
