I am planning on introducing a function called "connect_if_none" that
checks if it gets passed a connection and if so, return it. If it gets
passed undef, it will establish a connection and return that one.
That way a user can simply write something like
my $conn = connect_if_none($scfg, $password, $conn);
and not worry about it.
