In the following case: >>> class Foo: ... _Foo__a = 100 ... __a = 33 ... >>> Foo._Foo__a 33
I think this behavior, for a user who does not know the convention, could be a surprise. Should be raising an exception (in order to inform the user the transformation of the name __a have been replaced an existing name) a possible --explicit-- alternative?
Another question is: where is the place in which this transformation occurs? Is it at the parser level, before the dictionary attribute is gave as argument to the metaclass?
I looked at the documentation: http://docs.python.org/3/reference/lexical_analysis.html http://docs.python.org/3/reference/expressions.html#atom-identifiers but it is not clear when this transformation happens. -- Marco Buttu -- https://mail.python.org/mailman/listinfo/python-list
