extends

allow merge case

union A switch(long) {
    case 1:
    case 2: //< allow
    case 3:
        u8 a;
};

allow using simple_type_spec in template parameter

module MyTemplate <typename T, struct S, long m> {
                                      //  ^ allow
};

allow custom prop appears in value_box_def

custom valuetype A a; // value_box_def
// ^ extend grammar
