Right, the format string is in general a run-time value, so you can't always catch this situation at compile-time.

 But how many times do you want to ignore some of the arguments listed? Even if this happens (and I don't remember needing this), I think it's not common enough to justify so permissive semantics at run-time.

Recently Andrei A. has expressed some opinions on this topic, but I don't remember the bug report number.
