libmoosex-declare-perl 0.43-1 (amd64 binary) in ubuntu bionic

 MooseX::Declare provides syntactic sugar for Moose, the postmodern object
 system for Perl 5, inspired by Perl 6. When used in your code, it sets up the
 "class" and "role" keywords that can be used to declare classes in an elegant
 and concise manner.
