Thanks, Rob!
Yet, I'd really like the proto core team to answer these. My questions
more far-reaching than they may seem to be.
It's well known that javascript isn't object-oriented in a strict
sense, it's prototype-oriented. And to make it truly to support OOP
paradigmas can be perhaps the goal the language has never been
supposed to reach in the first place. However, understandably, it
remains a challenge for every professional js-programmer, to do
something in the OOP direction.
I'm no novice here, I've seen a lot of bad OOP implementations. And
I'm sure you all have. It'll be a drag to devise a clever inheritance
mechanism to only inflate the valuable library and to never really use
such inheritance for the reason it seems so complex and un-
maintainable for real-world applications. I'm tracking prototype's
progress almost since its conception on the web. And so forth, it
seems, Object.extend ans Class.create served well. I hope that
whatever becomes out of elaborating it [=base part], will be as robust
and useful as its predecessors.
That's why I'm offering my share in it. If you're interested to have a
look, just ask. No - no. Our code I'm offering is far from ideal,
however in the hands of prototype team it may really become something.
As it always have.
Thanks.
Best regards,
Andrew Revinsky
