what problem are you trying to solve?
the limit would check only that the right number of
argument bytes are consumed, but not that they are
interpreted correctly. print("%s %d", 1, "hello") would
still crash, as would print("%s", 1, "hello").
#pragma varargck is more precise and can be
done at compile time instead of needing to wait
until the code trips at run time.
