in thread Trying to optimize de-referenced hash slice without scope variables...

Autovivification shouldn't fill in the data structure as I access it? So both the accesses should produce the same data structures (that's autovivification work, I guess), and Data::Dumper should produce the same result in both cases.

BTW, here is the result, again:

perl -MData::Dumper $data = { a=>'b', c=>'d', e=>'h', i=>'j' }; $_[3] = { a=>'b', c=>'d', e=>'h', i=>'j' }; print Dumper @$data{'a','c','e'}; print "\n"; print Dumper @{$_[3]}{'a','c','e'}; print "\n";
and the result was:
$VAR1 = 'b'; $VAR2 = 'd'; $VAR3 = 'h'; $VAR1 = 'b'; $VAR2 = 'd'; $VAR3 = 'h';
exactly as expected. I'm confused. What's the problem with auto-vivification? Its supposed to fill in the "gore details", it isn't?

Thank you for your time and patience!
