Thanks for the bug report - this is fixed for the next release (the actual problem here is we were looking for instance members for special methods, which we shouldn't do). You can actually get the fix now if you get the latest bits from IronPython on http://www.codeplex.com, but we should have a release real soon now.

Subject: [IronPython] Overloading __getattr__
We have a problem with IronPython and overloading __getattr__, and use of the python magic methods (double underscore).
To illustrate the problem :
def __getattr__(self, name):
raise AttributeError("Go Away")
On CPython it does this :
On IronPython :
Traceback (most recent call last):
File C:\Personal\Python Projects\modules in progress\ironpython\test.py, line 6, in Initialize
File C:\Personal\Python Projects\modules in progress\ironpython\test.py, line 4, in __getattr__
AttributeError: Go Away
We are trying to overload __getattr__ and getting calls to __hash__, __len__, __gt__ etc sent there in various places.
All the best,
