Like Antoine, I consider the pure Python implementation to be

reference, so its behavior is idiomatic.
To this native English speaker, 'behavior is idiomatic' is not idiomatic
;-). The word 'idiomatic' refers to mode of expression, not mechanical
behavior. Perhaps what Eric is saying is that the behavior of the
reference implementation is by definition correct. Yet we have learned
over the years to be more careful about what cpython behaviors
constitute 'python' and which are incidental implementations.
'Improving the test suite' sometimes mean segregating the two.
What is *idiomatic*?
Expression that seems natural to a native speaker of a language,
dialect, or subculture.
The question you address is which behaviors of a Python OrderedDict are
part of the definition and which are implementation-specific, and
whether the tests need improvement.
