We considered this when designing AS3, but passed on it as being one too
many uses of 'dynamic'. We felt that using the dynamic-ness of the class of
the type annotation gives the user sufficient control in most cases. And
anyway, without a static verifier ES4 won't be affected by this particular
design trade-off.
