(accumulate f init ind)
Similar to `reduce`, but accumulates intermediate values into an
array. The last element in the array is what would be the return
value from `reduce`. The `init` value is not added to the array
(the return value will have the same number of elements as `ind`).
Returns a new array.
(reduce string "ha" ["ha" "ha" "ha" "ha"]) # => "hahahahaha"
(accumulate string "ha" ["ha" "ha" "ha" "ha"]) # => @["haha" "hahaha" "hahahaha" "hahahahaha"](reduce + 1 [2 3 4]) # -> 10
(accumulate + 1 [2 3 4]) # -> @[3 6 10]
