Yup, one's been able to collapse exactly like that for more than twenty years.
https://metacpan.org/source/LWALL/perl5.002b3/pod/perlref.po...
That's from 5.002, from last century, and it wasn't introduced on 5.002.
Beginning from v5.20, one's also been able to use the postfix dereference syntax, turning:
say join "\t", @{ $foo->{bar}[0]{quux} }
into:
say join "\t", $foo->{bar}[0]{quux}->@*;
Whether that's better or worse, it's debatable.
