Hi,

the documentation about Special method lookup

claims:

Does this statement holds for every special method mentioned in section 3.3
Special method names
?


You should generally take such statements at face value.  Unless you 
find specific exceptions mentioned elsewhere, 'no guarantee' means just 
that, regardless of how any particular implementation behaves today.
