I recently noticed nested struct capture its context by reference

obviously doesn't do a deep copy of its context.
So my question is, is there a way to deep copy the context of a struct?
Can you show a small example? This seems to work:
auto foo(int i) {
struct S {
int foo() {
return i;
}
}
return S();
}
void main() {
auto s = foo(42);
auto s_copy = s;
assert(s.foo() == 42);
assert(s_copy.foo() == 42);
}
