[go-nuts] C variadic macro equivalent in Golang?

[minforth]

C allows comma-separated argument lists via variadic macros. Whereas AFAIK 
golang allows only variadic arguments of the same type.
(Please excuse if I am wrong, I am considering myself a golang newbie)

C demo program that prints:   -- -- 1 and 1 1 and 1

// ###### C variadic macro test

#include <stdio.h>

#define PR(...) if(df){printf(__VA_ARGS__);\
                if(ef)fprintf(stderr,__VA_ARGS__);}

// Flags
int df=1, ef=1;

int main(void) {
  PR("-- ");
  PR("%d and %d ",df,ef);
}

// ###### End

How would one implement an equivalent PR(...) "function" in Go ???
