Note however that while setting $_ ($ARG with English) simplifies regexp
matching
Speaking of which...

Could we please move to using this everywhere:

    use English qw( -no_match_vars );

That would give all the benefits of readability without performance
penalties. The load time seems to be neglible:

    $ perl --version | grep v5

    This is perl, v5.10.1 (*) built for x86_64-linux-gnu-thread-multi

    $ time perl -e 'print'

    real    0m0.005s
    user    0m0.000s
    sys     0m0.004s

    $ time perl -e 'use English qw( -no_match_vars ); print'

    real    0m0.017s
    user    0m0.008s
    sys     0m0.008s
you have to take care to use
quoted
+sub maildomain_sanitize {
+	local $_ = shift;
   local $_ = shift;

and not

   my $_ = shift; 

And to use 'local'.
As done.

The Perl 5.12 now finally allow my'ing of $ARG too. But maybe we don't
switch to it just yet...
