in thread Is auto-dereferencing worth forcing upgrades to newer versions of Perl?

And it works right now.

Not in core, it doesn't. (Though I wish it did.)

But anyway, you're missing (or intentionally misdirecting) the point that the justification is not technical, but aesthetic.

And what do you care? If you don't like a given feature (and there's no global performance cost involved in implementing it in the first place), just don't use it.

Some people like new features and some don't. Some like evolution and some like stability. Fine.

My point was that these are individual decisions to be made by individual developers. Expecting "everyone" or "no one" to use a given feature is unrealistic. There's an adoption curve. It happens. No big deal.

    Wish granted.

    Really, it does:

    #! perl -slw
use strict;

package Thing;

sub new { bless [], $_[0] };
sub push { push @{ shift() }, @_ }

package main;
use Data::Dump qw[ pp ];

my %x = ( foo => [ map Thing->new, 1 .. 10 ] );

$x{foo}[0]->push( 1,2,3 );

pp \%x;

__END__
C:\test>junk66
{
  foo => [
           bless([1, 2, 3], "Thing"),
           bless([], "Thing"),
           bless([], "Thing"),
           bless([], "Thing"),
           bless([], "Thing"),
           bless([], "Thing"),
           bless([], "Thing"),
           bless([], "Thing"),
           bless([], "Thing"),
           bless([], "Thing"),
         ],
}

    That's 5.10, but it's worked right back to 5.6.1 (and probably before, but that's before my time with Perl.)

    (And if aesthetics is the current, important criteria for the future of Perl5, there are plenty of other areas that definitely rate attention long before this.)

      It doesn't work on unblessed references, which is what the auto-deref feature does work on. (I thought you were referring to autobox.)

        No. I wouldn't touch autobox with yours let alone my own :)
