libvar-pairs-perl 0.004001-1 (s390x binary) in ubuntu hirsute

 Var::Pairs exports a small number of subroutines that add some Perl 6
 conveniences to Perl 5. Specifically, the module exports several subroutines
 that simplify interactions with key/value pairs in hashes and arrays.
 .
 If the autobox Perl module provided in libautobox-perl package is installed the
 object-oriented methods corresponding to the subroutine-based interfaces can be
 used.
