How can I convert an array to a tuple?

Question

I just want to convert an array into a tuple in Swift; something like the following:

>>> myArray = [1,2,3,4,5]
>>> mytuple = tuple(myArray)

It's actually quite possible, if you are willing to do some low level magic. I don't think it works if the tuple has a collection type, though. This is mainly for interacting with C libraries.

typealias TupleType = (UInt8, UInt8, UInt8)

var array = [2, 3, 4] as [UInt8]
var tuple = UnsafeMutablePointer(malloc(UInt(sizeof(TupleType))))
memcpy(tuple, array, UInt(array.count))
