Valac: Compiling into C code: Expected semicolon in the wrong place

What?! A semicolon in a bad place, that's for sure! Why would I want to put a semicolon *BETWEEN* the class initialization and its members? Isn't the whole point of a class to *HAVE* different members?

Here is my class:

Code:

public class Gtk.rgba : GLib.Object {
    public class fg_color : GLib.Object {
        private uint8 red;
        private uint8 green;
        private uint8 blue;
		
        //Constructor
        public fg_color(uint8 r, uint8 g, uint8 b) {
            r = red;
            g = green;
            b = blue;
			
            uint full_color = red * green * blue;
        }
    }
	
    public class bg_color : GLib.Object {
        private uint8 red;
        private uint8 green;
        private uint8 blue;
		
        //Constructor
        public bg_color(uint8 r, uint8 g, uint8 b) {
            r = red;
            g = green;
            b = blue;
			
            uint full_color = red * green * blue;
        }
    }
	
    //Toplevel constructor
    public rgba(var bg, var fg) {
        bg = bg_color;
        fg = fg_color;
    }
	
    public static void init(double alpha) {
        double alpha_t = alpha;

        //Here's where the error is
        for (alpha_t > 0; alpha_t < 1; ++alpha_t) {
            fg_color fg_increment(red++, green++, blue++);
            bg_color bg_decrement(red--, green--, blue--);
                                 ^ //The compiler is telling me to put a semicolon *HERE* <yawn>.
        }
    }
}

Prove that the compiler is wrong. I.e. take the language spec/standard, read it, show the relevant paragraphs and prove that the compiler is incompatible with the language spec/standard.

Had it been "C", I would have said "read the C99 standard". Notice, that the languages you are trying to use change, but your problems stay the say. The main problem typically is: expectations based on nothing.
