Not so seldom we have situations in which an occurring error is tollerable. Typically we wrap such a situation in a try/except clause.

But this can also be done differently, if we use an appropriate class:

---

class ignore_error(object):
    def __init__(self):
        pass

    def __enter__(self):
        return self

    def __exit__(self, exc_type, exc_val, exc_tb):
        return True

---

Now we can write:

---

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

---

without causing an error.

Note that the entire block after "ignore_error" is ignored in case of an error. Like the part that follows a "try".
