I wouldn't use MacOS as an example of this. Apple has already deprecated
including any scripting languages in their base install as of last year's
Catalina release. Until they actually remove them I find it highly unlikely
they will do anything other than just be frozen at the Perl version they
currently include which is 5.18.4 or 6 major versions back. -- Darren Duncan
