( #3333=superdoc: print w/replies, xml ) Need Help??
Hah! I finally understood something! Probably something I shd have understood a while ago... namely that a hash in array context is an array. So When I do
@list = qw (one two three); %args = ( arg1 => 'string', arg2 => 5, arg3 => \@list ); sub1(%args); sub sub1 { print "$_\n" for @_; }
I get
arg1 string arg2 5 arg3 ARRAY(0x17656b4)
Obvious when you think about it. I mention it here more to fix it in my own mind than in the faint hope of enlightening others, who are probably way ahead of me. But it does make sense for me of a lot of stuff I've been doing on trust, not 100% knowing why it works... like this way of passing arguments to HTML::Template.
