This takes the idea of inheritance and converts it into a "magic" laden assignment statement.
Huh? use base was invented to address those concerns. Check it out.

    I am familiar with base, but the base pragma is an addition to the perl OO syntax not part if the actual syntax itself. Like I said, I would rather it be either a keyword like extends or it be part of the class declaration process (of which there really is none, its just a package declaration, and bless makes it a class).

      "You keep using that word ("syntax"). I do not think it means what you think it means."

      There's no reason you can't think of use base as a keyword with a space in it.

      Note, I'm not necessarily disagreeing with your complaint about the mechanics of Perl's OO... although I happen to be quite fond of it.

        You keep using that word ("syntax"). I do not think it means what you think it means.

        Syntax, as far as I know (and I am no linguist) is the arrangement of "words" into "sentences" as described by or conforming to a grammer. When I say "perl's OO syntax", I mean the various keywords/operators in perl that when combined in a certain way, create OO perl code. What do you think I am meaning when I say "syntax"? Please explain, or correct me if I am wrong in my thinking.

        As for use base, yes you can look at it as a keyword with a space in it, but that does not make it a keyword. If you were stuck on a desert island with just an interpreter and no modules, you would have to revert to the ugly @ISA = qw(Bar); form (although I suspsect you would likely just implement your own base pragma).

        Please note as well that I make my living writing OO perl code and enjoy I enjoy doing it very much. But having to work with it every day has convinced me that there is room for improvement.
