libipc-shareable-perl binary package in Ubuntu Focal amd64

 This perl module provides a tie() interface to System V IPC shared memory
 segments.
 .
 IPC::Shareable allows you to tie a variable to shared memory making it
 easy to share the contents of that variable with other Perl processes.
 Scalars, arrays, and hashes can be tied. The variable being tied may
 contain arbitrarily complex data structures - including references to
 arrays, hashes of hashes, etc.
