in thread Secret Perl Operators: the boolean list squash operator, x!!
He probably means something like this:
exists $hash{ foo } && exists $hash{ foo }{ bar } ? $hash{ foo }{ bar +} : ()
In this case, switching to x!! will cause $hash{ foo }{ bar } to always be evaluated, which will cause $hash{ foo } to be autovivified even if the condition is false.
