You can't. Object.opEquals is not nothrow, so object.opEquals is not 
nothrow (note the former is the virtual member function, the latter is a 
global function which is what the compiler actually calls).

It is a legacy limitation. Until we get rid of all the Object base 
methods for things like opEquals and toHash, we will not be able to fix 
this.
