How to convert a string command line argument to an int?

[BoQsc]

I tried to use `std.conv.parse(args[2])`,

```
import std.stdio;

import std.conv;

  void main(string[] args){

	if (args.length > 1) {
		writeln(broadcastSettingChange(args[1]));
		if (args.length == 2) {
		// TODO: second argument needs parse to uint
			writeln(broadcastSettingChange(args[1], 
std.conv.parse(args[2])));
		
		}
		
	} else {
	
		writeln(broadcastSettingChange());
	}
	write(args.length > 1);


  }
```

### But I'm getting this error
