The name of that method implies that it would be reasonable to do:
getattr(object,index.getIndexedAttribute())=20

Is that a requirement?



I have some pluggable indexes which index properties of objects that are =
not=20
available as attributes, and where the property identity is not naturally=
 a=20
string.

Currently the id of my indexes contain the 'property identity' munged int=
o an=20
ugly string (Yes, even more ugly that "topic_txt" ;-) because I am=20
constrained by the syntax of python attribute ids.

Can I implement getIndexedAttribute() to return a nicely formatted descri=
ption=20
of the property identity?
