I think an example is in order. I'm going to code up a simple event dispatching algorithm in three languages. They'll have the same functionality. I consider myself fluent in all three, and I'll write them in the most consise and style-respecting way I can.

C++:

    #include 
    #include 
    #include 
    typedef void (*hndlr)(std::string);

    class Event {
      private:
        std::vector handlers;
      public:
        void Listen(hndlr handler) {
          handlers.push_back(handler);
        }
        void trigger(string arg) {
          for (std::vector::iterator i = handlers.begin(); 
              i != handlers.end(); i++) {
            (*i)(arg);
          }
        }
    };
    
    void h1(std::string arg) { 
      std::cout
Lua:

    event = {listeners = {}}

    function event.listen(self, handler) 
      if (type(handler) ~= "function") return end
      table.insert(self.listeners, handler) 
    end
    
    function event.trigger(self, arg) 
      for handler in self.listeners do handler(arg) end
    end
    
    event:listen(function(text) print("First handler got "..text) end)
    event:listen(function(text) print("Second handler got "..text) end)
    event:trigger("something happened!")
C#:

    using System;
    public delegate void HandlerDelegate(string arg);

    class Main {
      static event HandlerDelegate Event;
      static void Main() {
        Event += (arg) => { Console.WriteLine("First handler got" + arg); };
        Event += (arg) => { Console.WriteLine("Second handler got" + arg); };
        Event("something happened!");
      }
    }
Now, go ahead and say that choice of language doesn't matter. You might not need lambdas, or first-class functions, or event handlers, and a good programmer can make the same algorithm "work" in any language. But by choosing a more powerful and expressive language, you can get those algorithms done in a way that's more readable, maintainable, and faster to code, which in the end is what really matters.

Also fun: The only one of these that works when a callback removes itself from the event list in its own callback routine is C#. You get a hanging iterator in C++, and removing items from a table mid-iteration in Lua is undefined (though in practice usually works).

To make this case work properly, the place I work for has a 335 line C++ template class. This is all time that the developer could have spent actually building our product.

The C++ version could be greatly simplified by using boost::bind. It'd still be shorter and clearer than a Java equivalent that had to bung in anonymous classes and other crap to create a proper dispatch.

Your point, however, totally stands.

Oh sweet jesus finally collection literals. Why did it take more than 10 years to decide to bring in something so convenient? One reason I sometimes find Java repulsive is the fact that it takes so much redundant code to do something so simple. Why do they hold back on such syntactic sugar?

Oh god. Please no, collection literals are the worst idea ever. Making up special rules for some special classes in a language? What the fuck!?

Syntactic Sugar: Collection literals List people = {"Frank", "Mary", "Satan"}; I find it breathtaking this isn't core yet. I was writing test fixture support code for 1.4 to easily and DRYly generate lists of up to 10 items, which required 10 copy-paste functions each with a different number of arguments. 1.5 came along and made it possible to easily do it with one function thanks to varargs, but it's 6 years later a…

What's wrong with List.of(...)?

I think adding special syntax rules is a pretty bad idea.

Good luck with that wish.

I would have to lookup the serious academic paper that says peel is technically unparsable in the same ways as PL/1. I think to date there have been two aborted perk on java efforts Not sure if perl6 has the same properties mind.

I wish I had checked that over I just saw that my phone mangled perl twice
