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.

But you should know that `alias this` is generally regarded as an anti-pattern; it's great for a quick hack to get things done, but in the long term, you should probably refactor your code to avoid it.
