import std.format, std.range;
void main()
{
string line = "12 13 14";
// arrays work
int[] ary;
formattedRead(line, "%(%d %)", &ary);
assert(ary == [12, 13, 14]);
// output ranges
auto app = appender!(int[])();
formattedRead(line, "%(%d %)", &app);
assert(app.data == [12, 13, 14]);
// delegates
int cnt = 12;
auto dg = (int v) { assert(v == cnt++); };
formattedRead(line, "%(%d %)", dg);
