all you are saying is true BUT
I do not think we should blame C for something which really is not nice.
I know not many share my opinion but the brave speaks out nevertheless ;)

IMHO the interpreter should raise an expression when a String is passed to
%d (as you asked OP rightfully not to do so).
Early Failure, please, *early*.

BTW who is talking about sprintf I am talking about "%" a very rubish
construct.
