I am working with a collection of sequences ...(e.g.

6 /3 /7 /f /4 /3 /2 /4 /5 /7 /3 /6)...)
I want to partition the sequences into groups of 4, but when I try the
following or something similar it fails saying either partition or
apply is being passed the wrong number of args.
(map #(apply partition 4 %) coll)
partition takes a sequence as a single parameter.
I think what you might want is something like this:
user=> (def coll (list (range 10) (range 20 30) (range 40 50)))
#'user/coll
user=> (map #(partition 4 %) coll)
(((0 1 2 3) (4 5 6 7)) ((20 21 22 23) (24 25 26 27)) ((40 41 42 43)
(44 45 46 47)))
user=>
