Re^3: Cor—An object system for the Perl coreby perlfan (Priest)

(moved from OOP and the Perl core per suggestion in rt)
I am not sure how these Quests work, but I will offer something to this notion. Why have all attempts to add a MOP or some sort of "object system" to Perl failed?
The answer for me is simple. The resulting attempts have, rather than created an idiomatically consistent linguistic interface to Perl, created monstrousities that have lead us away from perl. Moose and all its bastard children are perfect examples. Not only have they simply created new declarative and unrecongizable mini-languages with-in perl, but they have spurred wasted time and talent in totally separate languages with-out. Moose (and it's elk), Perl 6/Rakudo/Pugs/Parrot/MoarVM, etc have become poisoned pills that shattered the community and distracted us from true enlightenment. I've watch this train wreck for nearly 20 years and each passing year only confirms for me that this is true. Every fight, every new release, every name change.
Recently I have seen something that gives me true hope that an idiomatically consistent approach to objects in Perl is possible. That thing is Util::H2O. I am not saying it is perfect, but hot dang it's exciting to see what can happen as a post-modern approach to OOP begins to spring to light.
One last thing I has point out is any successful OOP in Perl shall recognize a couple of things:
This is an important PDL concept: PDL stores its data arrays in simple perl variables ($a, $x, $y, $MyData, etc.). PDL data arrays are special arrays which use a more efficient, compact storage than standard perl arrays (@a, @x, ...) and are much faster to access for numerical computations.What is my point? Well, this is important, too: up to now people who have championed OOP in Perl have been people who arguably HATE Perl. What shall succeed will be done so by thoses who LOVE Perl and everything about it. Maybe it's the person who wrote Util::H2O. Maybe it's someone who has yet to be born. I have no idea. But I do know that this is how I feel after 20 years of being immersed in Perl.
ReferencesPDL, which I believe has the right approach and is the right place for introducting some shared memory type things (if it's not there already, been a while).
