libsub-strictdecl-perl binary package in Ubuntu Oracular s390x

 Sub::StrictDecl provides optional checking of subroutine existence at compile
 time. This checking detects mistyped subroutine names and subroutines that
 the programmer forgot to import. Traditionally Perl does not detect these
 errors until runtime, so it is easy for errors to lurk in rarely-executed or
 untested code.
