Thank you, that is what I was trying to convey.

I think the most important thing to do when working with structures that may contain anonymous hash refereneces is to avoid using tests that access a possibly non existent hash reference key by name, which, as far as I know, is the only way to cause autovivification. I am not sure what, other then ref could even be used. This link provides some extended examples on the subject.

[ambrus]: 1nickg: obviously the gamers don't know. but anyway, I need the whole room backlit, because watching a monitor in a dark room (like many people do) is tiring for my eyes, even more so than doing it in a lit room.
[1nickt]: ambrus I agree. I suspect one's eyes are always trying to adjust across the boundary between very bright and very dark ... like a camera's autofocus struggling to choose the target.
