Well, it strikes me that some of what the dynamic camp likes
is the actual *absence* of declared types, or the necessity
of having them. At the very least, requiring types vs. not requiring
types is mutually exclusive.
But again, my dynamic kung fu is very weak, so I may not know
what I'm talking about when I represent the dynamic side.
