        The StarBindFlags describe how the '*' and '&' in pointers/references
        should be bound in the string representation.

        This also applies to rvalue references ('&&'), but not to
        pointers to functions or arrays like in

          void (*p)()
          void (*p)[]

        since it seems to be quite uncommon to use spaces there.

        See the examples below. These assume that exactly one
        flag is set. That is, it may look different with
        flag combinations.

                 e.g. "char *foo", but not "char * foo"

          \value BindToLeftSpecifier
                 e.g. "char * const* const", but not "char * const * const"
