[Zope-dev] "Record" instances and therefore Z SQL brains behave strange

[Dieter Maurer]

For the archives:

  "Record" instances and instances of derives classes
  are very strange objects.

    *  they do not have a "__dict__" attribute

    *  they define a "__setattr__" that allows to modify
       the "Record" attributes but raise an Attribute Error
       if one tries to modify any other attribute.

  As a consequence, there are no instance attributes beside
  that defined by the record schema.

  This applies especially to Z SQL Method brains.
  They cannot use instance attributes.

  What a mess!
