A macro can't do this, it must return a single form. But the `apply`
function can do something similar in the context of a function call.
(apply foo '(1 2 3))
is the same as
(foo 1 2 3)

What do you mean by "unwrap a list"?
If you mean something where:
(foo (unwrap 1 2 3)) == (foo 1 2 3)
Then I'm afraid this can't be done. A macro returns a single data structure.
