Even worse, now you need to elaborate why you're sure that it's a lost cause and add arguments to your critic.

That's not my argument, but why do I need to elaborate? What's unclear about "this has been promised since 2011, and it hasn't happened yet, so why should I believe it's right around the corner"?

Of course you could watch the videos first and tell us afterwards where the logical fallacies are. This might be easier.

Why? What's changed in the design since 2011-2013?

When I profiled Rakudo, I proposed a simple grammar change to freeze the definition of .ws to a well-understood character class so that every grammar rule wouldn't have to go through a method lookup between tokens. Larry said no. (I can't remember if that was a 30% or 40% speed improvement in the Rakudo test suite.)

NQP is pretty speedy. It's not bad for a dynamic language. Rakudo isn't speedy. Last time I looked, that was inherent to the design.

Furthermore, the reason we wanted to get as much Parrot code out of C as possible in Lorito is to learn the lessons of JavaScript implementations: the more code written in JavaScript, the faster it can go. Nothing I've seen in Moar suggests it's taken that approach. Maybe it can, but until it does, I don't expect it will improve performance in the large by orders of magnitude.

Hi,

I'm late in replying because sometimes I think I need to build up the necessary know-how in order to give an adequate answer.

Unfortunately this often leads to silently starving threads, so here an emergency before time-out response. ;-)

You can't expect us - the general public - to know the detailed discussions of Perl6's genesis.

If you claim it's not easily possible in the future , then it's appropriate to list arguments.

The opposing side can counter this with other arguments. That's how scientific discussions work.

> Why? What's changed in the design since 2011-2013?

Again I don't know, I have to rely on experts exchanging arguments which I can decompose into bits I understand.

You've done this now, at least partially°. Thanks.

Once I find the time I'll try to read up on

• NQP
• Moar
• Rakudo
• Lorito
• Parrot
• JS's internal model
to have a better understanding.

°) you could also have had a look into the videos and enlighten us how these concepts collide with your POV.

I don't expect that at all. I expect you to be able to understand my argument:

• Moar was made, in part, to speed up Rakudo.
• Moar began in April 2012.
• One of the criticisms of Parrot that lead to Moar was "10 years of development led by different architects at different periods of time (each of them with good ideas, I should add) led to a fair amount of baggage, as it would in any software project." (The most charitable reading of this is that a single architect for Moar might lead to less baggage, but let's be realistic -- any project more than a couple of years old will have baggage.
• Rakudo dropped Parrot support four and a half years ago. (Let's assume that Moar and Parrot had sufficient feature parity at that point.)

If feature parity was a milestone (and I expect it was) and speed is a goal (as we have heard), that's at least four and a half years to focus on speed, assuming that the new architecture of Moar only makes speed possible and doesn't confer any measurable speedups on its own. So where are the dramatic speed improvements? What feature or capability that exists in September 2019 justifies all of the churn and drama of the past 8 - 9 years by giving me something usable I didn't have in 2011?

It's especially interesting to read the comment on Patrick's post that "Rakudo needed NFG support and Parrot refused to provide it", because that's utter nonsense. But I suppose I'm fairly sensitive to opportunity costs and the community costs of not delivering something that's been long promised.
