Maintain Key Order as specified in Struct?

[pixelwiz]

I know key order in JSON is not relevant and can't be dependent on, but for debugging and readability purposes it would be great if the order of key/value pairs in the JSON object would be the same as the Struct from which it was serialized.

If you submit the PR then I'll consider merging it. ;)

This should be easier to implement now that you can create ordered structs in CF2016+, right? StructNew("ordered").

Some messaging services (and JSON-to-XML APIs like Authorize.net) require JSON keys to be in a specific order. Using "ordered" would allow for the JSON objects to be faithfully serialized & deserialized in the same received order.
