[Zope] using getProperty and catching Unauthorized

[Casey Duncan]

So long as the string doesn't contain a space, then it is always interned by Python:

>>> a = 'Not Found'
>>> b = 'Not Found'
>>> a is b
0
>>> a = 'Unauthorized'
>>> b = 'Unauthorized'
>>> a is b
1

So it works if the string exception doesn't contain a space, otherwise you're hosed ;^)
