0. when dot object opeator is enable, use small sign and add sign [<+]  be 
equivalent to [.] for string concat mark.
     compatibility is achieved through configuration switches.
     syntax :
          >>> $a = 'str0';
          >>> $a .= 'str1' <+ 'str2' <+ 'str3' <+ $str_var <+ strcall();
          the concat equal sign[.=] not change

1. use dot mark[.] same with [->]
     syntax:
          >>> $a = new stdClass;
          >>> $a.b  =1;   same with $a->b = 1  when dot object opeator is 
enable in php.ini
          >>> $a.get();    same with $a->get()  when dot object opeator is 
enable in php.ini

2. colon [:] same with [=>] in array declaration statement
     syntax:
          >>> $a = [ 'b' : 1, 'c' : 3 ]; same with $a = ['b'=>1,  'c' => 3]

3. another class declaration statement,  cant not use [extends] and [implement] 
keyword
     syntax:
          >>> class Objects(ParentClass): Interface1,Interface2 {} 
          same with
          >>> class Objects extends ParentClass implement Interface1,Interface2 
{} 

         anonymous class
         >>> $obj = new($arg1,$arg2) class(ParentClass) : implement 
Interface1,Interface2 {} 
         same with
         >>> $obj = new class($arg1,$arg2) extends ParentClass implement 
Interface1,Interface2{}

5. another class method declaration statement,  omit [function] keyword is 
allowable
     syntax:   
          >>> public method_name($args) {}
          same with
          >>> public function method_name($args) {}

6. restriction public magic method synax sugar, omit [public][function] 
keywords and duoble underline[__] is allowable, only __get()  __set() __call() 
__callStatic() __toString()  __sleep()  __wakeup()  __serialize()  
__unserialize() is availabled
          syntax:
          >>>  class A {
          >>>       get() {
          >>>        }
          >>>        call() {
          >>>        }
          >>>  }
          same with:
          >>>  class A {
          >>>       public function __get() {
          >>>       }
          >>>        public function __call() {
          >>>        }
          >>>  }
