(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 + 1 [2 3 4]) # -> 10
(accumulate + 1 [2 3 4]) # -> @[3 6 10]
