```d
import std.stdio : writeln;
enum Flag : bool { no, yes }
alias Traditional = Flag;
alias Color = Flag;
void hello(Traditional traditional, Color color) {
if (traditional && color) {
writeln("\x1b[31;1mhello world\x1b[0m");
} else if (traditional && !color) {
writeln("hello world");
} else if (!traditional && color) {
writeln("\x1b[31;1mHello, world!\x1b[0m");
} else {
writeln("Hello, world!");
}
}
void main() {
hello(Color.yes, Traditional.yes); // this is wrong, but
accepted
}
```
