libobject-declare-perl binary package in Ubuntu Xenial amd64

 Object::Declare exports one function, declare, for building named
 objects with a declarative syntax, similar to how Jifty::DBI::Schema
 defines its columns.
 .
 In list context, declare returns a list of name/object pairs in the
 order of declaration (allowing duplicates), suitable for putting into a hash.
 In scalar context, declare returns a hash reference.
 .
 Example: function for defining some declarative object
 .
  sub do_declare { declare {
      column x =>
          is rw,
          is Very::Happy;
      } };
