Re: How do you check if a key exists without creating it ?

You're just falling into autovivification. Check for existence of the lower level first if you don't want it autocreated:

use Data::Dumper;
$x = {};
1 if ( $x->{Y} && exists $x->{Y}{X}  ) ;
1 if ( $x->{Z} && defined $x->{Z}{A}  );
print Dumper $x;
