Right.  And I believe that Perl's Hashtable is the same.  I see this
has the LCD behavior (which happens to align nicely with 'function')
thus key order shouldn't be part of the generic model -- as we'd like
most generic YAML tools to operate on native Perl and Python constructs
directly without requiring a wrapper.

Right.  But this is a "formatting" issue, and I'm sure we will have
functions in the YAML toolset which work on the "syntax" model
where key ordering, node style, and other formatting information is
available.  This model will obviously require a DOM or third-party
object to store the YAML-specific attributes.

Of course, "C" language doesn't have a generic "container" so
that binding will have to use a YAML specific structure.  But "C"
isn't a scripting language (which is our target audience)

Best,
