You're having a compile-time literal vs. a runtime object here. That's 
kinda a big difference, you know? I wouldn't want to have my runtime 
object initialization to be somewhere in class declaration scope. Kinda 
hard to measure the performance then.

Oh, besides... this wouldn't even be in static constructor, but rather 
the normal constructor.

class A {
     Port httpPort;

     this (int port = 80) {
         httpPort = new Port(port);
     }
}

I'd like to keep the "verbosity" of initializing class members at 
runtime as-is.
