Re: Whether to use local()

in reply to Whether to use local()

My question is whether you should be concerned with scope if $new_mail needs to be shared between sub update_mail_list and sub read_mail_list etc.

One trick I sometimes use to share a variable among multiple subroutines, without making it a package variable is to enclose all of them in a block.

{
    my $new_mail;

    sub update_mail_list
    {
        # uses $new_mail
    }

    sub read_mail_list
    {
        # uses $new_mail
    }
}

What do monks think about this style?
