If the function's defaults will always match the default 
initializers of the struct itself,
```d
struct Options {
     bool silenceErrors = false;
}
void someFunction(Options option = Options.init) {
	writeln(option);
}
```
else:
```d
struct Options {
     bool silenceErrors = false;
}
void someFunction(Options option = Options(silenceErrors: true)) {
	writeln(option);
}
```
