So can C.

This is one area of concern. Just as big a problem for the OS case is
that the hidden constructors/destructors may fail. You can write C++
code carefully to avoid these things but it can be hard to see where the
problem is when you miss one.

C at least makes it verbose, but we trade that for poorer typechecking
and visibility control.
