SF patch 568629 by Oren Tirosh: types made callable. These built-in functions are replaced by their (now callable) type: slice() buffer() and these types can also be called (but have no built-in named function named after them) classobj (type name used to be "class") code function instance instancemethod (type name used to be "instance method") The module "new" has been replaced with a small backward compatibility placeholder in Python. A large portion of the patch simply removes the new module from various platform-specific build recipes. The following binary Mac project files still have references to it: Mac/Build/PythonCore.mcp Mac/Build/PythonStandSmall.mcp Mac/Build/PythonStandalone.mcp [I've tweaked the code layout and the doc strings here and there, and added a comment to types.py about StringTypes vs. basestring. --Guido]
