generator: Remove use of 'has_key' function

Browse Source 
The code 'XXX.has_key(YYYY)' must be changed to be of
the form  'YYY in XXXX' which works in Python2 and 3

As an added complication, if 'YYY in XXX' is used against
an object overriding the '__getitem__' method it does not
work in Python 2.4. Instead we must use 'YYY in XXX.keys()'
