Also if you pass null to a template it completely looses its implict conversion
abilites. See following example.

void foo(Object o){
}

void fooHelper(T)(T o){
  foo(o);
}

void main(string[] args){
  fooHelper(null); //can not implicitly convert void* to Object
}

This also stops std.conv.emplace to work correctly with constructors you want
to pass null to.
