2008-05-18 | Paul Boddie | file changeset files shortlog | Revised the rules around attributes and contexts, based on new observations documented in the methods.py examples. Added a context attribute to Attr instances in order to properly simulate the revised rules. Added context changing as values are added to namespaces. Added missing context generation in invocation code generation. Tidied up the formatted representations of data objects. Fixed local variable positions. Tidied up Getattr processing when inspecting modules. Extended the tests to cover attribute access rules. |
