I don't think I forgot anything.

I was genuinely asking whether Abigail thought that this was something that I should be testing for in my programs or just another of those many perl quirks that it's good to be aware of but probably pointless actually coding tests for.

Abigail tends to have a very dry sense of humour and I couldn't tell if this was a serious concern for everyday use or not from his post, so I asked.

We could put checks in our code to make sure that someone hasn't re-defined our defined constants, but that would render them pretty pointless.

So, my question remains -- should I be checking the return from ref for definedness every time I call it, or is the possibility of a reference blessed into package 0 (zero) or package '' sufficiently rare and unlikely that I can reasonably ignore the possibility?

If I understand your problem, I can solve it! Of course, the same can be said for you.
