If we put $x=(1,2) then we get 2 without the error message.
Can someone please explain why?
Yes, perl places the last item in the list into the variable. That's
why the others are "useless".
Try:
my $x = ( 1, 2, 'this one' );

Programming is as much about organization and communication
as it is about coding.
I like Perl; it's the only language where you can bless your
thingy.
Eliminate software piracy: use only FLOSS.
