I've been running 2to3's fix_callable over 2.6's stdlib to remove -3 warnings due to callable() usage; 2to3 replaces callable(x) with has_attr(x, "__call__"). Unfortunately, this breaks code that wants to run callable() on old-style classes (like test_builtin), because old-style classes don't have a __call__ attribute (new-style classes do, however).
How should this be handled? I'm tempted to just add __call__ to old-style classes for 2.6, but Neal Norwitz thought that might break some user code. Any other thoughts?
