Re: hash deref confusion: Intermediate Perl

in reply to hash deref confusion: Intermediate Perl

Are they actually saying that you can have a list of keys ("qw(wins places shows losses)") and set the values by setting this to the list "@standings"?? Really?

Why not just try it and see?? A toy experimental program takes less than a minute to create and run. Really!

>perl -wMstrict -le
"use Data::Dump;
 ;;
 my $self = { foo => 'bar' };
 my @standings = qw(1 2 3 4);
 ;;
 @$self{ qw(wins places shows losses) } = @standings;
 ;;
 dd $self;
"
{ foo => "bar", losses => 4, places => 2, shows => 3, wins => 1 }

Of course, but you are taking this out of context. I would have had to know @$self{ qw... was a hash slice which was my real problem. I assumed the line worked, I did not understand the syntax.	[reply]
