This is rather cool -- I especially like the implied feature of deriving the
type of the result from the type of the outermost level of the object.  I
would be +1 on making zip/braid a sequence method rather than a function.

I don't like the idea that the police department seems bent on keeping
a pool of unarmed victims available for the predations of the criminal
