These are because of a fix I made.  When we checked overrides, we were treating
(dynamic) -> dynamic as fuzzy.  So you got that weird co-variance, where you
could override an (dynamic) -> dynamic with an (int) -> int, but you couldn't
override an int -> dynamic with a dynamic -> dynamic.  We weren't implementing
the dsend on method calls of dynamic (which we would have to do to make this
sound), and I think the general sense was that there was no reason to treat
these as fuzzy arrows.
