How about this: give the property instance a method that changes a
property from read-only to read-write.
No parens, no frame magic. As a small bonus, the setter function would
not have to be named the same as the
property.
class A(object):
@property
def foo(self):
return 1
@foo.setter
def set_foo(self, value):
print 'set:', value
