So I would say that any code that *sets* $_ is, by definition, wrong.

I feel this is not a Golden rule. Setting $_ has its uses, especially when one would like to do regex operations not wishing to declare intermediate variables. It is generally wise to localise $_ before setting it. A good example of this kind of usage can be found here.

in thread "$_" vs. $_ by argv
