Constructors in Ceylon

  I'm still waiting for you to retract that, now that I've 
  conclusively demonstrated that Ceylon's constructors are 
  totally different to—and more powerful than—Scala's.

Eh. What?

A) You conveniently left out the other part of the sentence.

B) I already commented on that topic very early on, and clarified:

  Ok ... I'm really starting to believe you when you said you 
  didn't look into that other language, because there is 
  practically no benefit in doing it the way Ceylon does.

To which you – confusingly – replied with:

  I never said that. Please don't put words into my mouth.

So what do you actually want?

  Ceylon's constructors are totally different to—and more 
  powerful than—Scala's

Yep. I didn't deny that. It's a good thing though, because Ceylon's approach isn't very good in terms of language complexity.

I never said I've never looked at Scala. I think you can tell from my responses to you in this thread that I'm in fact quite knowledgeable about Scala. What I said was that I had not looked closely at how Scala does constructors and that they were not an inspiration behind the design of constructors in Ceylon.

Whatever, your attack on me was totally uncivil and unjustified, as you now realize, which is why you're backpedalling it so furiously. You've never interacted with me before, and so coming in here with a blazing personal attack was completely unreasonable behavior. I think you see that, so let's just drop it now.

> Ceylon's approach isn't very good in terms of language complexity.

Here's another assertion for which you simply have not provided evidence. How are Ceylon's constructors more "complex" than Scala's constructors? The actual syntactic weight of both constructs is almost identical. And in terms of complexity, the factory-method-on-a-companion-class pattern is significantly more complex in terms of ceremony than doing the equivalent thing in Ceylon.

Look man, stepping back a second, I can see that you're clearly a fan of Scala and that Scala is something you love and enjoy. That's great! But Scala isn't perfect and other languages can have good ideas too. I highly recommend you spend some time learning Ceylon, since it has a bunch of awesome things in it that I know you'll love: the things we can do with union and intersection types, disjointness, abstraction over tuple and function types, etc, are just beautifully elegant and powerful. Don't let the fact that you love Scala blind you to other ideas.

I don't think it's a blind love, but all those things will ship in one of the next versions of Scala, too.

Given there are some things I can't just suffer anymore, like unreadable Generics (<>), required ; and "Type ident" syntax, maybe Ceylon just isn't for me. :-)

Well it's really lovely and encouraging to see Ceylon exercising such a strong influence on Scala. Makes me very proud.
