Wouldn't we reuse the existing routines and simply add %@ ?

What do you mean ?  __attribute__((format (NSString, 1, 2))) works
on Apple (using LLVM I think, I don't have an Apple but I know it's
there) and it works as expected.  The standard example is NSLog 
(in much the same way as the standard example of the printf format 
is printf) and that is very well-defined.  GNUstep has NSLog and I can't
wait for the compiler to check that the arguments passed to NSLog
match the format string. ;-)

And since I implemented format attributes for methods, we should immediately
be able to have the compiler check [NSString -stringWithFormat:] as well ...

Thanks
