Re: Can I tell a sub to take $_ instead of @

sub foo {
    # changing $_ is not a good idea
    local $_ = $_;
    print "\$_ is currently: $_"
}
foo foreach qw(one two three four);

__output__

$_ is currently: one
$_ is currently: two
$_ is currently: three
$_ is currently: four

Because $_ is global you should be able to access it from anywhere (but be careful not to mess with it!).
