I was quite astonished! I put an $0 = 'xyzzy"; statement in my Perl code and I'll be, ps -ef shows xyzzy in the process table! I am shocked and don't know why this could happen! I would have never thought that $0 was a writable variable. My brain was thinking along the lines of C and its char** argv, which is normally used as "read only", but that's not what is happening here.

I guess you could save: my $saved = $0; or make a { local $0; $0 = 'xyzzy'; other stuff}, but I'm not sure why that would be useful?
