In connect(), before $connect_meth, just as connected() is called in that method after $connect_meth.

	$dbh->connected(@orig_args);
	unless ($dbh = $drh->$connect_meth($dsn, $user, $pass, $attr)) {

It's not my needs. Someone is creating a CPAN module I think. His needs were met by connected(), but I think that connecting() would be useful as well.

That would be cool. I, alas, have a very short supply of tuits these days.
