Is there an implementation which does not interpret the objects 
in the array:

Case 1
```
[{"A":"A","A":"B"}] -> [
     {
         "A": "B"
     }
]
```

Case 2
```
[1.0000000000000001] -> [
     1.0
]
```

Case 3
```
[99999999999999999999] -> 
std.conv.ConvOverflowException at ...Overflow in integral conversion
```
