Hello, What should the expected output be for:
void bar(void) { } sigc::slot<void> foo = sigc::ptr_fun(&bar); foo = sigc::slot<void>(); std::cout << bool(foo) << std::endl; ? I get "1" (using MSVC 2008 with libsigc++ 2.2.4.2), which surprised me. sigc::slot_base::empty() also returns true in this case. Is this subtle distinction intentional? The documentation for operator bool says: "Tests whether a slot is null, because the default constructor was used." On one hand, I didn't initialize the slot with the default constructor (although I did assign over it with a default-constructed slot). On the other hand, I think it qualifies as a "null slot".
