You could say the same thing about dynamic properties.  How come we don't  
split those out as opProperty?

opDispatch can do opBinary, it's a subset.  It makes no sense to define  
opDispatch(string s)() if(s == "+") I agree, but I don't see any reason  
why opBinary(string s)() would fail to compile...
