[C++-sig] Disallow adding attributes to wrapped classes from Python

[Stefan Haller]

Is there a way to make the __dict__ of exposed classes read-only?  I
fear it will be a common error for Python programmers to make typos when
setting attributes, and I would like this to generate an error rather
than silently adding a new attribute.

class_<Foo>("Foo")
    .add_property("foobar", &Foo::getFooBar, &Foo::setFooBar)
;

>>> foo.foobaz = 7   # oops: typo!
>>> foo.foobaz
7
