Re^5: how ! operator works

So I looked at the code to answer your question.

Thanks! I searched the code myself today with no luck. I postoponed it for the weekend but now you have resolved this, I'll just have to stick to something else to do :)

My answer is more or less an educated guess. If you want to look around to confirm or for fun, PL_sv_no is the SV returned when a builtin wants to return something false. An interesting puzzle would be to see if you can manage to lower the refcount and display it at the lower refcount using Devel::Peek's `Dump`.	[reply] [d/l]
