Variadic functions?
-------------------

C is not a simple language.
There are some reasons why.

C, since K&R, supports variadic functions.
But does it really need to?
Note that B didn't have it, and neither did pre-K&R C.

It's handled very confusingly in C anyways.
va_list, va_start, va_arg, etc.

Variadic functions are probably the least bad way to implement something like printf though.
But the interface for such really could have been done better.
