Did you test this with the sub{}-example I provided in order to show context dependency?

Nope. I know it does exactly what you said it does. What it doesn't do is show what jdporter's solution has a problem. That would surely involve using jdporter's solution.

where would preservation of %_ (jdporter mentioned $_) usually be of some importance?

jdporter mentioned *_, not $_.

And localizing %_ would be "of some importance" when %_ is changed, like in the parent of the post to which jdporter replied. The same applies to all global variables.
