switch with repeating cases?

[acppdummy]

I have some cases in a switch statement sharing common code. Would this work?

                switch(mycase){
                    case 0: { code for case 0; } break;
                    case 1:
                    case 2: {
                        common code for case 1 and 2;
                    }
                    break;
                    case 2: {
                        code only for case 2;
                    }
                    break;
                }
