AFAIU, deriving from boost::noncopyable disables _accidental_ object
copying.
Is it possible to implement a clone() const member function of the object
to _explicitly_ get a copy of the object?
Perhaps deriving boost::noncopyable makes it totally impossible to ever
get a copy of an object without resorting to byte copy.
To avoid creating copies accidentally consider making copy constructor explicit.
struct Foo {
explicit Foo(const Foo&) {}
};
void Bar(Foo);
int main() {
Foo foo;
Bar(foo); // Error, implicit copy.
Foo copy(foo); // OK, explicit copy.
}
