This is a consequence of my implementation that others probably don't have.  When decoding mt5, I always keep a set of [key,value] tuples until all of the items have been decoded.  Then, if the keys are all strings, I convert the tuples to a JS Object, otherwise I convert them to a Map.  If I've already converted to a Map in mt5 processing, it's too late to (for example) throw an error if there is an unexpected duplicate key.
