Because objects are mutable Python by its nature does not resolve
member/property references until they occur within the code.  Consider
the following example (which is valid functional Python):

class foo(object):
    setup = False

f = foo()

def bar(f):
    if f.setup:
        f.baz = "hi"
        print f.baz
    else:
        f.setup = True
        print "setup"

bar(f)
bar(f)
