## extends

### allow merge case

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

### allow using simple_type_spec in template parameter

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

### allow `custom` prop appears in value_box_def

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

### allow omit param_attribute

```idl
interface A {
    void f(uint8 b);
};
```

### allow rust style oct number

```idl
const u8 A = 0o3;
```

### allow binary number

```idl
const u8 A = 0b010101;
```

### allow octet in typedef_spec

```idl
union A switch(octet) {};
//              ^ allow
```

### allow comma at last of enumator

```idl
enum A {
    A,
//   ^ allow
};

bitmask A {
    @position(0) a,
//                ^ allow
};
```

### allow ignore 'name='

```idl
@DDSRequestTopic("RobotRequestTopic")
//               ^ allow ignore `name=`
interface RobotControl {
    void command(Command com);
};
```

### allow ignore '=xx' in annotation
