( #3333=superdoc: print w/ replies, xml ) Need Help??

I am not sure I understand your point. I think you are trying to say that

$class = ref($class) || $class;
is no better/worse than
my $class = shift; bless {}, $class;
which is quite true, and since that is also a common idiom which will produce the same issue, then maybe that is not so good either.

In all cases, $class is undef, and when bless is passed undef it blesses into main. It might (and I stress might, because I am not so sure of this) make sense if when bless encountered undef in its second argument, that it treated it as a one-argument bless instead (which would result in blessing into the current package).
