Further, when the format string is a literal like the one used in the 
program, the compiler can in theory determine at compile time that the 
format string does not match the rest of the arguments:

     readf (" %s, &die");
     // "No argument for %s"

This is a desired feature but dmd does not have this yet. Since dmd 
provides the front end to gdc and ldc, they don't have this feature either.
