[Chicken-users] UNLIST a list of lists!?

[Bahman Movaqar]

Happy 2015 CHICKEN'ers!

I have a procedure which accepts a variable number of lists as the
arguments:

  (define (foobar . lists) ...)

Now, in some part of my code I need to zip 2 lists and pass the result
to "foobar".

  (define lis1 (list 1 2))
  (define lis2 (list 10 20))
 
The result of "zip" is, correctly, a list of lists.

  (zip lis1 lis2) -> ((1 10) (2 20))

However I need to pass the result of "zip" as 2 separate lists to
"foobar"; I need to *un-list* it.

  (foobar (1 10) (2 20))

Is there any standard way to do that? TIA,
