Hello and happy 2013,
Something I noticed earlier today is that some C versions of stdlib modules
define their name similarly to the Python version in their PyTypeObject.
Some examples: Decimal, xml.etree's Element. Others prepend an understore,
like _pickle.Pickler and many others.
What are the tradeoffs involved in this choice? Is there a "right" thing
for types that are supposed to be compatible (i.e. the C extension, where
available, replaces the Python implementation seamlessly)?
I can think of some meanings for pickling. Unpickling looks at the class
name to figure out how to unpickle a user-defined object, so this can
affect the pickle/unpickle compatibility between the C and Python versions.
