Why haxe is a better php (1) - mixin - annotations - array deferencing - closure_and_chaining_function_call

annotations.hx

//support for annotations
// https://wiki.php.net/rfc/annotations

@class_annotation({a:1,b:2})



class Main {

  @range(1,100)
  public static var value:Int=0;
  
  @before({func:'before_func'})
 public static function main() {

   
 }




   
}

array_deferencing.hx

//support for array deferencing
// https://wiki.php.net/rfc/functionarraydereferencing

class Main {
  
 public static function main() {

  trace(get_fruits().a);
  trace(get_list_numbers()[0]);
   
 }

 public static function get_fruits() {
   return {
     a:'apple',
     j:'juice'
   }
 }
 
 public static function get_list_numbers() {
   return [1,2,3,4,5];
 }
   
}

closure_and_chaining_function_call.hx

//support for real closure (without explicit variable in closure) and chainable function call
// https://wiki.php.net/rfc/fcallfcall

class Main {

 public static function main() {

   var sum=function(a) {
     return function(b) {
       return function(c) {
         return function(d) {
           return a+b+c+d;
         };
       }
     };
   };

   trace(sum(1)(2)(3)(4));
   
 }
  
}

using.hx

// Haxe support traits with using that add Methods
// at compile time based on the type of the first parameter of static method of class
// used as mixin

class StringMixin {
  
  public static function addPPP(s:String):String {
    return  s + "ppp";
  }
  
}

//---------------------------------------------------------------------

using StringTools;
using StringMixin;
class Main {
  
 public static function main() {

   var x:String="i am a string";

   "i am another string".addPPP().addPPP().addPPP();\

   x.addPPP(); 
   
 }
   
}
