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);
