No, a non-const reference cannot be bound to a temporary -- clang is correct to
diagnose this. But the other implementations are correct too: because this
error occurs in a template, no diagnostic is required until the template is
actually instantiated.
If you add an instantiation:
void f() {
VariableList<int, float>().ConnectAllToAll();
}
then GCC and ICC also reject, and MSVC also rejects under /permissive-
(standard-conforming mode).
