<pre>
    I know that the `?:` is not standard, but llvm/clang supports it, afaik. But somehow it seems to convert the type

```
bschubert2@imesrv6 test>cat elvis.cpp
enum my_status_t {
    MY_SUCCESS = 0,
    MY_FAIL1 = 1,
    MY_FAIL2 = 2,
 
};

my_status_t func1()
{
    return MY_SUCCESS;
}


my_status_t func2()
{
    return MY_FAIL1;
}

int main(int argc, char **argv) 
{ 
 (void)argc;
    (void)argv;

    my_status_t status = func2() ?: func1();

    return (status == MY_SUCCESS) ? 0 : -1;
}
```

```
bschubert2@imesrv6 test>g++ -g -W -Wall -Werror -o elvis elvis.cpp
bschubert2@imesrv6 test>echo $?
0
```

```
bschubert2@imesrv6 test>clang++ -g -W -Wall -Werror -o elvis elvis.cpp
elvis.cpp:24:17: error: cannot initialize a variable of type 'my_status_t' with an rvalue of type 'int'
 my_status_t status = func2() ?: func1();
                ^ ~~~~~~~~~~~~~~~~~~
1 error generated.
```

Why is it converting from my_status_t to int?
