Simplified:
import std.stdio;
struct Widget {
private int[] array;
this(uint length) {
array = new int[length];
writefln("ctor called : %s", array.ptr);
}
this(this) {
writef( "this(this) called: %s", array.ptr );
array = array.dup;
wr
Compile this and see, (it's crazy!):
import std.stdio;
struct Widget {
private int[] array;
this(uint length) {
array = new int[length];
}
this(this) {
writeln( "this(this) called" );
array = array.dup;
}

No, and this is actually a terrible idea. See

The wiki says there was a dmd fork that attempted this 5 years

In fact, it can nowadays be. You just have to mark it so, with a
lambda:
void main()
{ import std.stdio;
auto myArray = [2, 3, 5, 6];
