I checked:
```d
import std.stdio,
std.range,
std.algorithm;
struct N(T)
{
T last, step, first;
bool empty() => first >= last;
T front() => first;
auto popFront() => first += step;
}
void main() {
auto r1 = N!size_t(10, 1, 1);
auto r2 = N!real(15, .5, 10);
```
and it seems to work as I said.
Thank you for checking again, but it is important to be solution
oriented. How about Tuple?
Yes, it might be wise to use a tuple in this case:
```d
//...
auto tuple = a.zip(b);
tuple.writeln;
// [Tuple!(int, dchar)(97, 'd'), Tuple!(int, dchar)(98, 'e'),
Tuple!(int, dchar)(99, 'f')]
tuple.map!(num => num[0].to!dchar).write;
tuple.map!"a[1]".writeln; // abcdef
}
```
