Hi

I'm perplexed; I'm using CGI to receive a list of parameters, which might arrive under one name or another. So I wrote:

my @things = $q->param('t') or $q->param('things');

I wanted the list of parameters in t, or if that parameter is absent, the ones in things. It's all good if t is present, but fails otherwise, with an empty list. I narrowed it down to the following test case:

sub foo {
    wantarray ? () : 1;
}

sub bar {
    wantarray ? (3, 4) : 3;
}

my @thingies = foo() or bar();
warn @thingies; # Expected (3,4) here, got ()
my @thingies = ( foo() ) or ( bar() );
warn @thingies; # Expected (3,4) here too, got ()

I don't understand! If I were using ||, sure, that puts the calls in scalar context; however, with or, why doesn't the first sub get called in list context, return false with the empty list, and let the second sub get called? What am I missing?

Thanks
