How so?  In decades of using perl, I've only seen one case where even 
major version revs did not maintain complete backwards compatibility in 
the core language, that being when @ in double-quoted strings started to 
be interpolated.  But yes, if I were to expect perl to control my 
machines, I'd provision a separate instance of it for that purpose so 
system updates can't be suicidal.  Sort of like using static libs in C 
programs that need to always work.
