copying const struct

[Jack Applegame]

Why this doesn't compile?

class Foo {}

struct Bar1 {
	const(Foo[]) member;	
}

struct Bar2 {
	const Foo member;	
}

void main() {
	const Bar1 bar1;
	const Bar2 bar2;
	Bar1 b1 = bar1; // ok
	Bar2 b2 = bar2; // cannot implicitly convert expression (bar2) 
of type const(Bar2) to Bar2
}
