Is there a prettier way to do this?
Thanks in advance.
```d
import std.range;
auto getFirst(R)(R range)
if (isInputRange!R)
{
if (range.empty) return ElementType!Range.init;
else return range.front;
}
```

Is there a nicer way to get the first element or typeof(element).init from a range?
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
