Agreed. But what about just using @_ = @_ instead of local @_? Assignment to @_ is what the docs prescribe for breaking the aliasing. Any reason for preferring one approach over the other?

I said local $@, not @_. There's no point to localizing @_, that's your input! You'd copy stuff out of it if you needed that behavior.
