Yes, but these are uncommon class names anyway. If unsure one can always
look at the generated C code.

Yes, connect_signal_full is only needed if you want to customize the
signal connection process. But usually you don't need that.

For small programs you can put them into the global namespace. But if
you have many callbacks you will end up with a polluted global
namespace. So you might want to organize them in classes. And for
non-trivial callback methods, if you wish to access instance methods in
order to modify the state of the surrounding object, the callbacks must
be instance methods.
