well no: the fastest possible way would probably be hand-optimized

i don't think that in practice this would matter though.
an [array-drip]¹ implementation in Pd-vanilla should be O(n).
an [array drip] implementation in C should be O(n).
sure, the abstraction implementation will perform worse by a (constant)
factor but the complexity stays the same which is the important part.
i assume that the cases where you do need that extra speed boost are
rather seldom, and do not warrant an extra built-in object.
¹ it always causes me pain to see the name "drip" used so widely.
