First, opDispatch is a template, so it's not dynamic dispatch unless 
your template effectively do its dispatching at runtime. I don't think 
Andrei was proposing dynamic dispatch here.

And since we're talking about dynamic dispatch: for the overridden 
methods to work when you create a D subclass of an Objective-C class, 
all methods have to be declared at compile time, even though in 
Objective-C they're dynamically bound. The goal of the bridge is to 
expose Objective-C objects as D objects, and thus overriding must work. 
It'd be pretty useless if it didn't.
