Summary:

public subscript (subRange: Range<Int>) -> ArraySlice<Element> is not working.

This is from Xcode 7 beta 6 release notes

"For consistency and better composition of generic code, ArraySlice indices are no longer always zero- based but map directly onto the indices of the collection they are slicing and maintain that mapping even after mutations.

Before:

var a = Array(0..<10)
var s = a[5..<10]
s.indices
s[0] = 111
s
s.removeFirst()
s.indices

Try to run this code, it doesn't work.

Steps to Reproduce:
Make a playground, run the code. 

Expected Results:
It should work

Actual Results:
fatal error: ArraySlice index out of range

Notes:
Playgrounds is attached
