```
import std.stdio;
void main(){
auto a=new int[][] (0,0);
a~=[1,2];
a~=[3,4];
auto b= a.dup;
a[0]=[5,6];
a[1][1]=7;
writeln(b);
}
```
Program above outputs [[1, 2], [3, 7]]
Which means a[1][1] and b[1][1] point to the same memory location.
But a[0] occupies a different memory location as

You can implement deep copy using template recursion:
import std;
T[] rdup(T : U[], U)(T[] duped) {
return duped.map!(arr => arr.rdup).array;
}
T[] rdup(T)(T[] duped) {
return duped.dup;
}

byLine was the original implementation. byLineCopy was added later

auto tmp = File(filename).byLine();
`File.byLine` overwrites the previous line's data every time it
reads a new line. If you want to store each line's data for
later use, you need to use [`byLineCopy`][1] instead.
