libperlx-define-perl 0.101-4 (ppc64el binary) in ubuntu eoan

 PerlX::Define is a yet another module for defining constants.
 .
 Differences from constant.pm:
 .
  * Cute syntax.
    Like constant.pm, constants get defined at compile time,
    not run time.
  * Requires Perl 5.12 or above.
    If you're lucky enough to be able to free yourself
    from the shackles of supporting decade-old versions of Perl,
    PerlX::Define is your friend.
  * Only supports scalar constants.
    List constants are rarely useful.
    Your constant can of course be a reference to an array or hash,
    but this module doesn't attempt
    to make the referred-to structure read only.
  * Doesn't try to handle some of the things constant.pm does
    like declaring constants using fully-qualified names,
    or defining constants pointing at magic scalars.
 .
 Prior to version 0.100, PerlX::Define was bundled with Moops.
