C++ is a hack - Hackdot

I don't think the parent meant free as in "free()" - more along the lines of.

  Foo f;
  DoSomething(std::move(f));
  // can still use f here.

But if "Foo" was composed of unique_ptr (or shared_ptr), then those smart pointers would be nulled out after the std::move (due to the default move constructor)

So again, unless Foo f was composed of "raw pointers", even that kind of code is safe from "use after free" vulnerabilities.
