    Well, this is a stab in the dark, but when I see -1 being used in a fetch-from-array context, I tend to assume it's counting from the end of the array, not being treated directly as an index. Other than that, you aren't checking whether you're called on a reference or statically, which leads me to think that "ident $self" might not always return what you expect it to return.


    • Trust me. Once you see the bug, it's a forehead slapper -- if you've encountered this behavior before. It's something that folks often miss because it occurs so rarely, but it's a natural consequence of how Perl behaves.
