Test case

Hello,

    the order of the items seems inconsistent depending on key type.

    Please see the attachment.

Thank you,
Julian.

This is by design - associative arrays don't come out in key sorted order. We could change that behavior but that would make the function slower.

Quick hack

Would this quick hack make the function slower too ? Tested with a few unittests. It removes the segfaults from anytype[ushort] too.

Small correction.

The code assumes the set of numeric keys is contiguous, which is untrue for most associative arrays. For example, trying the code with [5:"a", 100:"b"] will fail.

Right. Back to slow indexes sorting.

Thank you,
Julian.
