well its a class behavior you're looking for so its not part of
mapper(). However, the mapper is applied to a class after the fact,
so theres no reason you can't add the "associationproxy" behavior in
the exact same way, i.e. monkeypatching after the fact, i.e.
class MyClass(object):
...
# elsewhere
mapper(MyClass, sometable, ...)
MyClass.someproxy = associationproxy(...)
if the only concern you have it that "MyClass.someproxy = XXXX" is not
two characters above its current position, inside the parenthesis for
mapper(), I'd suggest getting out more :).
