in thread How do I find out which variables I'm not using?

Yes nice! But note that, you don't need to use warnings qw(once) because the warnings provided by the warnings pragma are lexical, and you've got them enclosed in that block. So there IS some overkill there. I do like the block, so I wouldn't call the most of it overkill.

But does NAMING the block ever tempt you to goto LABEL??? I always am tempted, and grin mischieviously, and then I have to say 100 Hail Larry's to forgive myself.

    Both the label and the use() statement are technically unnecessary; or, conversely, the label and the block are unnecessary. I am aware of this but use them anyway. It's all part of the defensive progamming strategy.

    I would rather <insert your own nightmarish ineffability here> than type goto LABEL :-)
