If you replace "Java Killer/Successor" with "New Programming Language" I think the title makes a lot more sense.
For those of us for whom Java never was "alive" (not choosing to program in it), is it safe to ignore this new language? I would be interested in it more if they wouldn't pitch it as Java Killer.
Ceylon looks a lot (if not identical) to Scala. I was trying hard to find a differentiation, but couldn't.

Red Hat has put a lot of work into gcj, and was responsible for making Eclipse run on it. They've done a bunch of work on Iced Tea. They also have a bunch of Java applications they maintain/sell support for (JBoss is the big one). If this is actually a company priority (and not a side project), it could be a Big Deal(TM).
Although C# and Java do not suffer from the craziness that is C++, by virtue of requiring a class name, e.g.
template void myclass() { ... code ...};
...
myclass4>(); /* myclass? or syntax error? */
For heaven's sake, please use {} or [] or some other character which does not also function as an infix operator.
(Even APL and K, which overload every character in fifty different ways, don't mix grouping with infix operators)
let sum x y = x + y public final class Summer {
public static T Sum(T x, T y) {
return x.add(y);
}
}People, please learn from mistakes of the past. Using less-than and greater-than as template parameters was a horrible idea by Stroustroup, but was copied by Java and C#. Although C# and Java do not suffer from the craziness that is C++, by virtue of requiring a class name, e.g. template void myclass() { ... code ...}; ... myclass 4>(); /* myclass ? or syntax error? */ is unique to C++ - but still, all lexing/parsing…
let sum (x:'T) (y:'T) = x + y
Is it 'easy to read' as in let sum x y = x + y Or 'easy to read' as in public final class Summer { public static T Sum (T x, T y) { return x.add(y); } } Because I don't think that dreck in the bottom is 'readable', it's like giving construction workers a Fischer Price My First Hammer and expecting them to be able to build a house with it. If you're going to make a language like Java at least let programmers take the…
Assignment using := and string concatenation using adjacency aren't particularly new. edit -- further looking through the presentations ... They seem to have ditched the 'new' keyword, but not gone as far as having inferred typing which is a pity. Counter c = Counter(); would be better as c = Counter(); (edit: ignore this, the local keyword apparently triggers type inference). := and = are used to distinguish between…
What initializes a data structure should not care how the data structure was allocated. It's two functions one () -> T and T -> T allow them to be first class citizens.
If you want to combine them use a static method that simply invokes the initializer after the allocator (which is how it works anyway, and how new is implemented in both Ruby and Obj-C). And it's not like it solves any real problems as it's perfectly alright to have uninitialized and incorrectly initialized objects with current constructors.
