My C++ is a bit rusty. Does it manifest itself in the standard library as well? The problem with python (in my view) is that this behaviour is implemented in the standard library and therefor propagates to the 3rd-party libraries by convention.

Yes. For example for std::string `a = a + b;` will (at least notionally) create a temporary string and then use the assignment operator. `a += b;` will not do this.
