`(c-utake L U) → list`syntaxYields a list containing up to U items from the front of the given list, where U is a unary number.

Analogous to

`take`from SRFI-1, but uses unary numbers, and yields the entire list if it is too short.(ck () (c-quote (c-utake '(a b c d) '(x y z)))) ;; ==> '(a b c) (ck () (c-quote (c-utake '(a b) '(x y z)))) ;; ==> '(a b)
