2151 that this method takes an array, so all indices must be of the same type.
2152 If passed an array of <code>usize</code>s this method gives back an array of mutable references
2153 to single elements, while if passed an array of ranges it gives back an array of
2154 mutable references to slices.</p>
2155 <p>Returns an error if any index is out-of-bounds, or if there are overlapping indices.
2156 An empty range is not considered to overlap if it is located at the beginning or at
2157 the end of another range, but is considered to overlap if it is located in the middle.</p>
2158 <p>This method does a O(n^2) check to check that there are no overlapping indices, so be careful
