This is questionable sentence. On the foreach with tuple iteration, break
and continue have no effect for the unrolling.
void main()
{
import std.typetuple, std.stdio;
foreach (i; TypeTuple!(1, 2, 3))
{
static if (i == 2) continue;
else static if (i == 3) break;
pragma(msg, "CT: i = ", i); // prints 1, 2, and 3 in CT
writeln("RT: i = ", i); // prints only 1 in RT
}
}
So, I think that static foreach *cannot* support break and continue as same
as foreach with tuples.
