No.
I'm tempted to end this post here as an AOL one liner but I should justify
myself. Anything below here might be wrong.
$_ is a global. Therefore you can't make a temporary name for it which is
in scope when $_ is reassigned. I think things like map{} assign $_ in
dynamic scope nyway, don't they?
