The standard way would be to have the Processor class's __init__() 
method take two arguments which it would then assign to the appropriate 
instance attributes. You could, of course, provide default values if you 
felt so inclined.

Then you could just use

bar = Processor(foo.options.index, foo.options.output)

or something similar. That's better anyway, as it seems to make the 
coupling more explicit. What would you do if the index and output values 
were just stored in plain variables?
