Description
Eve (http://python-eve.org/) writes mongo documents containing the field :_created". It uses this to hold a timestamp for the document creation time. When I retrieve this object, the call to the model constructor files in base/document.py line 722 looks like this:
obj = cls(__auto_convert=False, _created=created, __only_fields=only_fields, **data)
At this point, data is a dict containing a key "_created" so this call fails because there are multiple values for the keywork "_created".
Is there any easy way to use a different internal keyword other than _created for this purpose, so that it does not clash with what is in the database? Or is there some other way around this?

Research direction
Start at base/document.py line 722 and reproduce retrieval of an Eve document containing the _created field. Trace how the model constructor receives created and data, then verify that documents with _created can be instantiated without duplicate-keyword errors.
