In a version 2 which I just sent to the librarian I also muse
that the whole get*() might just simply stink and tied hashes
(or hash refs, now that you mention it) might be much more natural
interface.
use Users;
my $u = {};
tie $u, 'Users';
if (exists $u->{damian}) { system ("rm -rf $u->{damian}->{home}") }
Just as a fictional example, of course :-)
