 Yes that's true. But nobody will give you a definite answer by referencing
to the C++ Standard. This is a really compiler dependent issue.

What you can do is inspecting the function signatures created in your
compiler's binary output. If you have an overload with 2 parameters, than it
means compiler applied some sort of optimization, otherwise, it will pass
and instance of the object, since the function with 2 parameters is simply
not there ;)
