+
+- enums
+
+```
+    enum Colors
+        $RED = 0
+        $GREEN = 1
+        $BLUE = 2
+    end
+
+    ...
+    $color = Colors.$RED
+    switch($color)
+        case(Colors.$RED)
+            console.printLine("RED")
+        end        
+        case(Colors.$GREEN)
+            console.printLine("GREEN")
+        end
+        case(Colors.$BLUE)
+            console.printLine("BLUE")
+        end
+        #-
+        case(Colors.$YELLOW)
+            console.printLine("YELLOW")
+        end
+        -#
+        default
+            console.printLine("No specific color selected")
+        end
+    end
+```
+
+- structures, which are data only
+
+```
+    # maybe, not sure if required 100%
+    structure CarData
+        $tireCount: Integer
+        $color: Integer
+    end
+```
+
+- structure data validations, which are type hinted interfaces alike
+
+```
+    # maybe, but looks good already
+    data Car validated-by CarData
+        private $tireCount  = 4
+        private $color      = "red"
+    end
+```
+
+- interfaces for class methods
+
+```
+    interface CarInterface
+        private $tireCount
+        private $color
+
+        constructor($tireCount, $color)
+
+        destructor()
+
+        method: dump()
+
+        operator: +: ($a, $b)
+
+        operator: +=: ($b)
+    end
+```
+
+- classes with optional interface and data validation
+
+```
+    class Car[ implements CarInterface [validated-by CarData]
+        private $tireCount  = 4
+        private $color      = "red"
+
+        constructor($tireCount, $color)
+            $this.tireCount = $tireCount
+            $this.color = $color
+        end
+
+        destructor()
+            $this.tireCount = null
+            $this.color = null      
+        end
+
+        method: dump()
+            console.printLine(
+                "$this.tireCount = $tireCount, " +
+                "$this.color = $color"
+            )
+        end
+
+        operator: +: ($a, $b)
+            return Auto(
+                $a.tireCount + $b.tireCount,
+                $a.color + "/" +  $b.color
+            )
+        end  
+
+        operator: +=: ($b)
+            $this.tireCount+= $b.tireCount,
+            $this.color+= "/" +  $b.color
+        end  
+    
+    end
+
+    #
+    $car = Car(4, Colors.$RED)
+    $car->dump()
+    #
+    $car = Car(4, Colors.$RED) + Car(4, Colors.$BLUE)
+```
+
+- Static member variables
+    - maybe by mapping to global variables
+    - Class::$classProperty would map to $$.___Class_classProperty
+
+```
+    class Class
+        static private $classProperty  = 4
+    end
+```
+
+- Static member methods
+
+```
+    class Class
+        static method: classMethod($a, $b)
+            console.printLine($a + " / " + $b)
+        end
+    end
+```
