The operative word being *whenever*. You're thinking of the i18n use
case, where the format string is separated from the arguments. I'm
thinking of the non-i18n use case, where the format isalmost always a
string *literal* adjacent to the arguments. I'm not at all convinced
that we should attempt to find a solution that handles both use cases;
most Python code never needs i18n.
