Re: when the keys are not unique: mapping and merging

Please be aware that you cannot rely on un-specified behavior.

Your YAML document may be parsed differently on another platform (or
even fail to parse !).
PyYAML may also change the behavior as a bug fix for another reported problem.

If you rely only on the explicitly specified features you are safe. If
you miss something in the specification (or in the implementation) you
may always ask a question here. Otherwise the parsers will get a bunch
of hacks which are difficult to maintain. (even though the hack may
look natural for one language or platform)
