Has AA .keys the same order as .values?

[Rene Zwanenburg]

Hi,

I need to interleave multiple arrays stored in an AA into a 
single array, and the keys of the AA need to be stored separately 
in the same order as the interleaved data. As an example:

auto aa = [
   "1" : [1, 2],
   "2" : [3, 4],
   "3" : [5, 6],
   "4" : [7, 8]
]

auto values = aa.values;
auto keys =  aa.keys;

//Store keys, and interleave values

I did a quick test and values has the same order as keys, but is 
this guaranteed to be the case?
