Ranges in general have an arbitrary length, whereas tuples have a fixed length that is known at compile time. So, it really doesn't make sense to convert a range to a tuple. You can create function that takes the first x number of elements of a range (probably throwing if the range is too short) and create a tuple from those elements, but it would be a bit of a pain to do, and it would generally be a pretty weird thing to do. A dynamic array would make a lot more sense than a tuple. - Jonathan M Davis
