I meant the latter. This information is needed in order to moderinise
Python code and also to have a reference for checking existing
code against a specific Python version.

I know. That's why I asked Raymond to add a Python version to
each of the modifications (basically pointing out in which Python
version this coding style became available).
Note that migration does not only include correcting code
which might break; it also covers code cleanups like what
Raymond is currently doing.
I somehow have a feeling that you are afraid of such a guide,
Guido. Is that so ? and if yes, why ? I think all this is valuable
information and worth publishing.
