It's probably an improvement, though as it is still at the
programmers' discretion, it is less useful for checking and more as
documenting. I remain ambivalent about whether exposing this level of
detail (complex typing) is a good idea, or whether imposing a small
fixed set of types (string/number/blob) is better.
