Hello,

This is my current solution but there must be a better way to do 
it in D

    T get(T)(T[] arr, size_t idx, T def = T.init){
      return idx<arr.length ? arr[idx]
                            : def;
    }

    .......

    Preset[string] presets;
    presets.keys.sort.take(1).get(0);   <-----

Is there a prettier way to do this?

Thanks in advance.

Oups: after fixing an error and making it compile the solution is 
even uglier:

presets.keys.sort.take(1).array.get(0);

```d
import std.range;

auto getFirst(R)(R range)
     if (isInputRange!R)
{
     if (range.empty) return ElementType!Range.init;
     else return range.front;
}
```
