in thread The default hash - accident, coincidence or conspiracy?
It is free for the using, if not taking. The local keyword is there to facilitate multiple code chunks using the same global variable independently. It works well enough for $_ and @_, it will work just as well for %_. (That's not to say it's a panacea, though.)
I don't understand why people think it's asking for trouble. It is no more asking for trouble than using $_ — and I sure wouldn't counsel anyone to avoid using $_. Quite the opposite, in fact.
That being said, there isn't any really good reason to use %_. The situations in which it would be the most obvious, "natural" name for a variable must be rare indeed.
