It's type propagation. Which can be seen as a form of inference or not, depending just where you draw the line.

So is auto, decltype and templates. In C++ we properly call it type deduction to distinguish it from actual H-M style inference which C++ lacks. The details of how it is called doesn't detract from parent's argument.

Yes. I hadn't meant my comment as argument on either side, just added context.
