This compiles, oh joy:
struct S {
int x;
int[] a;
}
S foo(const S b) {
S other;
other.x = b.x;
other.a = b.a.dup; // the dup is necessary here
return other;
}
void main() {}
The idea now is to find a way to encapsulate that manual copying & dupping into
some overloaded operator of S. But I have failed so far. Operator overloading
in D2 is not an easy thing, it needs training. (That's why I have recently
asked for the compiler to be strict to avoid wrong usages of the operator
overloading.)
