I think you two are in violent agreement as far as how Python is 
functioning, and the conflict is in the names given to the various 
pieces... I think a glossary would help (please correct me):

function:  callable code suite

method:  function that lives in a class

unbound method:  function that lives in a class

bound method:  callable wrapper around function that has been extracted 
from class that will supply the instance object to the function (note: 
Python does not save these, they are recreated at each lookup)


and here is where I think you two diverge:

instance method (Steven):  a bound method that has been saved into the 
instance __dict__ (no matter how created)

instance method (Terry):  a function that must be looked up in the class


Have I missed anything?
