autoadd class properties

[manstey]

Hi,

Cache is a pure OO dbase, so no ORM is required. Cache provides a
python equivalent for the Cache class, but not for the Cache
properties. Instead, the programmer has to know in advance the
properties and their type to get and set them. I want to wrap the
Python-cache class and add the Cache properties into the class, but I
don't know how to do this. Any ideas?
