Or to put it differently. Let there be a reason why a call to some function is not desired. Then the reason must be spelled in the language terms. E.g. this: variable value is used before being initialized and not this: initialization of this variable will be removed in the next version, don't use it ever! -- Regards, Dmitry A.
