It's not clear what you mean. The installer for development releases of perl (and release versions of perl built with -Dusedevel) install any binaries and script with the version number appended. On top of that you may have 3rd party install wrappers such as perlbrew, and OS vendors may also rename things they add to /usr/bin. I'm not aware of any changes to the way corelist is installed by perl itself.
