No, it has no effect on $1. I thought it would cause confusion! The

assigns a list to @f. The first element of the list is undef, and the
rest is the
result of applying the regex to $email, so it's the same as
my @f = (undef);
push @f, $email =~ /(.*)\@(.*)/;
and simply offsets the captured results by one. As I said, I can see no
reason to have
written it this way unless Mumia wanted $f[1] to correspond to $1 and
$f[2] to $2.

That was exactly my intention.
I thought I had to choose between that and setting $[ . Which is worse? ;-)
Anyway, I now think that a couple of scalars would have been better.
