[Mono-list] About Arrays of X

It won't work because int is an array of value types whereas
IComparable is an array of reference types. If you used 'int'
instead of Integer in Java you'd get the same problem.
The solution would be to box the ints by putting them inside an
IComparable array instead of an int array.
