Description
Does LGI support emitting existing signals on an object? I have an object type that has two signals associated with it according to the result of GObject.signal_list_ids(), but I do not know how to emit those signals on an instance of the object. I have tried calling obj:on_<signal>() but just get an error saying no 'on_<signal>'.

Research direction
Start by checking the LGI object and signal API around GObject.signal_list_ids() and the attempted obj:on_() call. Determine whether existing signals can be emitted on an object, then document the supported invocation or clarify the limitation and expected error.
