This list is available as part of the PropList.txt file in the unicode data, which ought to be included automatically in python's unicode database so as to get future changes. This I'm not so sure about. I changed the PEP to say that OtherID{Start|Continue} should be included. Whether the other properties should be added to the unidata module, I don't know - I would like to see use cases first before including them.

I only meant that the python's idea of Other_ID_* should be
automatically generated from the unicode data file, so that when
someone upgrades python's database to Unicode 5.1 (or whatever), they
don't forget to update a manually copied Other_ID_* list as well.

I do not believe it is a good idea for python to define its own identifier rules. The rules defined in UAX31 make sense and should be used directly, with only the minor amendment of as an allowable start character. That was my plan indeed.

I was voicing my support for your plan, in contrast to Talin's
comment that perhaps a more conservative subset would be good.
