  1. It uses "context" for something different from the "context"
     of Python Scripts (there "context" would be "object" and not
     "object.aq_parent").

  2. Accessing the acquisition parent via "aq_parent" is
     easy enough that no variable needs to be defined

  3. Access to the acquisition parent is a quite rare use
     case. No special variable is justified.

Are you sure, you need the acquisition parent (i.e. "object/aq_parent")
here and not the hiararchical parent (called "folder")?
