--- Comment #1 from Richard Smith <richard-l...@metafoo.co.uk> ---
"return r;" implicitly invokes the copy constructor of B to copy the return
value. You made that constructor explicit, so it can't be implicitly invoked
any more. Most of your example is an irrelevant distraction; the relevant part
is:
struct B {
B();
explicit B(B const &);
};
B f() {
B r;
return r; // error, can't return B here because there is no implicit copy
constructor
}
