Claim (false): Julia isn't multiple dispatch but overloading

@gbellomia

you need to make sure the actual behavior can be devirtualized, effectively reconciling with static overloading.

No, devirtualization is not the same as static overloading. Static overloading is determined by the types declared at the method-definition site, but devirtualization occurs based on the types inferred at the call site.
