2010-06-13 | Paul Boddie | raw annotate files changeset graph | Fixed exception attribute initialisation for translation errors. Reintroduced the _scope attribute on AST nodes in order to support supposedly harmless changes in scope (such as the "importing" of a built-in or global into a local scope where the name is redefined subsequently). Reorganised the tests according to the above shadowing policy change. Introduced tentative slicing support plus built-in functions that rely on slicing. |
