Missing scope on colons

[chbk]

: aren't scoped in the examples below. I suggest the following:

punctuation.definition.type.colon

enum class Color : char {red, green, blue};

punctuation.definition.visibility.colon (line 3)

class Rectangle {
  int width, height;
  public:
    int area() {
      return width*height;
    }
};

punctuation.definition.inheritance.colon

class Rectangle: public Polygon {};

punctuation.separator.method.double-colon for :: and punctuation.definition.initialization.colon for :

Rectangle::Rectangle (int x, int y) : width(x), height(y) {}
