I think in this case topNCopy should be able to generate a truly sorted output
(instead of a heap):
import std.stdio, std.algorithm, std.range, std.typecons;
void main() {
auto a = [10, 20, 30];
auto b = ["c", "b", "a"];
Tuple!(int, string)[4] sorted_ab;
writeln(a, " ", b);
topNCopy!q{a > b}(zip(a, b), sorted_ab[], true); // error
topNCopy!q{a > b}(zip(a, b), sorted_ab[]); // OK
writeln(a, " ", b);
}
