“Debug only” code that should run only when “turned on”
...make it static to persist the same value for the life of the program (or thread depending on your static memory model), or make it an ordinary instance var to control it over the life of an object instance. If that instance is a singleton, they'll behave the same way.

When to use reinterpret_cast?
...the applicability of reinterpret_cast vs static_cast . From what I have read the general rules are to use static cast when the types can be interpreted at compile time hence the word static . This is the cast the C++ compiler uses internally for implicit casts also.
