The only thing I would object to is the q{}. There's really no point
in using the q{} operator ... it just confuses the point here.
my $regex = join '', map { $num2chars[$_] } @digits;
And it could actually just as well be written as
my $regex = join '', @[EMAIL PROTECTED];
which IMHO is even clearer. "Join together the chars that belong to
the digits".
