libtest-trap-perl binary package in Ubuntu Xenial arm64

 Test::Trap is a Perl test module useful primarily (but not exclusively) for
 test scripts: a block eval on steroids, configurable and extensible, but by
 default trapping (Perl) STDOUT, STDERR, warnings, exceptions, would-be exit
 codes, and return values from boxed blocks of test code.
 .
 The values collected by the latest trap can then be queried or tested through
 as a special trap object.
