I would like to set function's default struct for a function in 
a way that it would be visible for the reader to see what 
options are set. Something like `Options option = 
{silenceErrors: false}`


Here is an example of what I would hope for to work but it 
surely does not work:

```
import std.stdio;

struct Options {
    bool silenceErrors = false;
}

void someFunction(Options option = {silenceErrors: false}){
        writeln(option);

}

void main() {
        someFunction();
}
```

Is it possible to make this part work in a simple way, maybe 
I'm using a wrong syntax here?
```
void someFunction(Options option = {silenceErrors: false}){
        writeln(option);

}
```

I would love to be able to use C style designated initialization 
everywhere too..

Recent version of D added named arguments so you can do something 
like:

```D
void someFunction(Options option = Options(silenceErrors: false))
```

I don't like the useless repeating "option option option", but 
that's D for you
