why doesn't formattedRead take args by ref instead of by pointer?

[Timothee Cour]

adding an overload would increases likelihood for bugs but could be
possible. The same holds for getopt.

Another question:
the documentation for formattedRead is quite sparse, how does it explain
the following behavior:

  string s="a1 a2 a3";
  string a,b;
  uint n=formattedRead(s,"%s %s",&a,&b);
  assert(a=="a1" && b=="a2 a3");
