As you can see above, the editor still doesn't work properly. The indentations are completely off when they are displayed. When I bring the text back into the editor, it looks completely right again.

Here again inserted as standard text:

---

class ignore_error(object):
    def __init__(self, *args):
        self.tolerable = args

    def __enter__(self):
        return self

    def __exit__(self, exc_type, exc_val, exc_tb):
        return exc_type in self.tolerable if len(self.tolerable) else True


with ignore_error(NameError, poser.error):
    actor = poser.Scene().Actor("not existing actor")
