Hi Jonathan,

  Sorry , not able to get you, can you please point our as to 
where we need to added the braces in the below example.

void main () {
Array!int Keycol;
static foreach(i; 0 .. 3) {
typeof(read()[i]) Datacol;
Datacol.insertBack(sort(read[i].dup[]).uniq);
foreach(k; read[i]) { 
Keycol.insertBack(Datacol[].countUntil(k));} }
writeln (Datacol[], Keycol[]);
}

From,
