117,Key Ordering,pschmitt@…,xi,"I dont understand how PyYAML reads YML files with ""Block Mapping"", (I call these ""Nested variables"" in my example):

{{{
>>> document = """"""
 Variable 1:
   x: a
   y: b
   z: c
 Variable 2:
   1: a
   2: b
   3: c
 """"""
>>> yml=yaml.load(document)
>>> yml.keys()
['Variable 2', 'Variable 1']

>>> yml[""Variable 1""].keys()
 ['y', 'x', 'z']
}}}

So it looks like PyYAML loads the document in reverse order, ""Variable 2"" is read before ""Variable 1"".  That's fine.  But why is yml[""Variable 1""].keys() in a random order?  It seems like it should either be chronological (x,y,z) or reverse chronological (z,y,x).

I'm having a hard time parsing tickets #29 and #116, which might be related... Can you offer up some insight?

PS:  Sorry if this is the wrong place for a question... I couldn't find a mailing list.
