I have another problem :

  1 import std.stdio;
  2 import std.string;
  3
  4 int main()
  5 {
  6   char[][] a = ["expected %s but found %s".dup, "42".dup, "32".dup];
  7
  8   writeln(format(a[0], a[1 .. $]));
  9
10   return 0;
11 }

Does not work :
$ dmd-phobos -run format.d
std.format.FormatError: std.format

but :

  1 import std.stdio;
  2 import std.string;
  3
  4 int main()
  5 {
  6   char[][] a = ["expected %s".dup, "42".dup];
  7
  8   writeln(format(a[0], a[1 .. $]));
  9
10   return 0;
11 }

does not seems to work either :
$ dmd-phobos -run format.d
expected [42]

Did I miss something ?
