I guess the question for me as to which is 'authentic' would be answered by
whoever defined $? first.
I dont know the history well enough to sort that one out though. So I'll
just say that *someone* is harshing my mellow...

Actually, the value returned by Perl is the more authentic value that
returns from wait(2), and also tells you whether core was dumped, and
the signal that killed it (if any). The shell sweeps all that away, and
loses information.
If anything, yell at your shell for lying to you. :)
