Then we are faced with a loss of functionality.  Suddenly there is no
way to define _IO or CTRL that is compatible with existing usage.  It
is reasonable to require us to rewrite our macro definitions; it is not
reasonable to require us to rewrite all our uses of the macro.  The
committee apparently recognized this when they provided # and ##, to
preserve the functionality of Reiser cpp substitution in strings and
/**/, but we need either a charize operator analogous to # or (my
preference) making subscripted string literals into constant
expressions in order to preserve the functionality of Reiser
substitution within ''.
