I've been using Perl since Perl 1, all the way to Perl 5. When the `local()'
declaration appeared, probably around Perl 2 or Perl 3 (I do not remember), I
started using it everywhere in an effort of protecting each procedure against
each other. It was also a convenient way to give names to formal arguments,
through "local(name1, name2, ...) = @_" as the first statement in a `sub'.
When "my(LIST)" appeared, one or two major releases later, I progressively
converted all my programs to use it, as it is more in the spirit of what
I wanted. The overall impression that was left to me is that a lot of
declarations are needed, anyway, if you consistently aim clean Perl scripts.
So, there is now an "our(...)" declaration in Perl? Hopefully, it will
not miss me much! :-) And who remembers the "own" specifier of Algol-60? :-)
