Thank you for your comments so far, and thank you for pointing out another technique to avoid autovivification (other than the autovivification pragma on CPAN).

I suppose some of your points will get less of an issue if you do get around to read the rest of the article. In particular, you may rest assured that I don't want to suggest new dereferencing operators.

To the contrary, the lightning-rod or fuse operator I was talking about would make such operators unnecessary.
