Created an attachment (id=694)
replacement for unittest of std.json

The only non-trivial unittest is commented out as "currently broken".
This is confusing: in fact, not the implementation but only the unittest is
broken.
The reason is, that the order of the name/value pairs in a JSON object is
unspecified:
the serialization uses foreach(name, member; value.object)!

The example just before the "currently broken" one is {"a":1,"b":null}:
as the result could also be {"b":null,"a":1}, this test is broken in theory,
but not (yet) in practice.

Please, consider to replace the broken unittest with the attached proposal.
