The following code does not compile because Zip cannot modify the second
tuple's member since it is immutable :
import std.algorithm;
import std.stdio;
void main()
{
immutable int[] A = [1,2,3];
immutable int[] B = [4,5,6];
auto AB = cartesianProduct(A,B);
writeln(AB);
}
The same thing appends here :
import std.stdio;
import std.range;
void main() {
writeln(zip([1,2,4,3], take(Repeat!(immutable(int))(2), 4)));
}
Is this a normal behaviour ?
