+ - Red Hat releases Ceylon language 1.0.0->

Submitted by Gavin King
Gavin King writes: Ceylon 1.0 is a modern, modular, statically typed programming language for the Java and JavaScript virtual machines. The language features:
  • an emphasis upon readability and a strong bias toward omission or elimination of potentially-harmful constructs,
  • an extremely powerful type system combining subtype and parametric polymorphism with declaration-site variance, including first-class union and intersection types, and using principal types for local type inference and flow-dependent typing,
  • a unique treatment of function and tuple types, enabling powerful abstractions,
  • first-class constructs for defining modules and dependencies between modules,
  • a very flexible syntax including comprehensions and support for expressing tree-like structures, and
  • fully-reified generic types, on both the JVM and JavaScript virtual machines, and a unique typesafe metamodel.
  • More information about these language features may be found in the feature list and quick introduction.

If you're a Java developer who's frustrated at the fact that Java is aging badly you should really give Ceylon a try.

First of all, it's designed with Java's strengths in mind but addresses its weaknesses.

It's designed to be readable, unlike some other newer JVM languages, so a large team of developers can work on its codebase.
It has a module system that Jigsaw was supposed to be 5 years ago.
It supports first class functions and higher order functions.
Unlike Java, variables are defaulted immutable and methods/classes are "private" by default.
Null is not a primitive type, therefore NullPointerExceptions are virtually non-existent as Optional is a first-class construct in the language.
Generics are reified and covariance and contravariance are supported in a much more coherent way than Java.
Ceylon also supports union and intersection types as well as type aliases, saving much of the boilerplate involved in simple subtyping.
The Eclipse IDE plugin is excellent and for all intents and purposes, production ready.

I know you've gone on record supporting closures in Java and have apparently supported them for a very long time.

I apologize then for being unfamiliar with the history behind Java closures, as it is badly documented on the internet (or my Google-Fu is weak, I don't know which).

So why do you think Java didn't originally have closures, why weren't they added instead of anonymous inner classes in Java 1.1, and what were the other roadblocks to Sun adding closures in the past.

FIrst of all, non sequitur. My question was what makes Apple different from every other patent holder? You didn't answer that question.

Second of all, what makes Apple a "once-creative company" that "wants to be a twisted old"?

Is there a problem with Apple's business model? If so, please enlighten me, because for a company to be #1 in market cap, they must be doing something right?

Has Apple stopped creating new products? The iPad came out in 2010, so I'd say the answer is no.

Does Apple have a great, modern technology stack? Among other things, considering that they maintain their own open source C-compiler tools, and they have by far the best consumer desktop operating system, I'd say the answer is yes.

So how is Apple declining? Because you feel their attempts to assert software patents supposedly mask an insecurity about their ability to innovate? Please.

It seems intuitively obvious to me, which means that it might be wrong. -- Chris Torek
