Update: My apologies! Forget what I have said, it was my observation was off, not yours. But it might be a better idea to demo your issue by using Data::Dumper.

use Data::Dumper; use strict; use warnings; my %foo = ( BAZ => 1 ); sub see_args { }; print Dumper(\%foo); see_args( @foo{qw(BAR BAZ)} ); print Dumper(\%foo);

It prints:

$VAR1 = { 'BAZ' => 1 }; $VAR1 = { 'BAZ' => 1, 'BAR' => undef };

Yes, autovivification is in working.

Your observation was off. In your original post, you were confused by the fact that the $ENV{TMPDIR} "appears" to have a value as you saw it through that sprintf. No, you didn't see the value of $ENV{TMPDIR}. Your sprintf printed a constant "<absent>", not the value of $ENV{TMPDIR}.</strick>
