Hi!  I want to process a collection 2 elements at a time using map.

My function accepts 2 parameters (a,b) and returns a result (c):

(myfcn [a b])

 => c

so I want to iterate myfcn over a collection and create a new sequence

for example let's say myfcn sums a and b, then i would like to do
something like this:

(map myfcn '(1 2 3 4 5 6 7 8)

=> 3 7 11 15

accept i get the error that myfcn is being passed the wrong number of
arguments, since map is passing them in 1 at a time.  How do I get map
to pass in 2 at a time?

thx!
