I need my struct to convertable to 'wchar'

[Zoda]

Hi, I need my struct to convertable to 'wchar' my struct looks 
like this
```d
struct ColoredChar {
     int[3] rgb;
     wchar ch;
}

// Existing functions looks like this
void doSomething(wchar ch) {
     ...
}
```
i don't want my existing functions to break so i need my struct 
to be convertable to a 'wchar', how can achieve this?

Thanks, Zoda.
