Hi perldigious,

tybalt89's suggestion appears to be Postfix Reference Slicing, which is part of the new Postfix Dereference Syntax, which says:

In Perl 5.20 and 5.22, this syntax must be enabled with use feature 'postderef'. As of Perl 5.24, no feature declarations are required to make it available.

Hope this helps,
