Perhaps it was obvious to everyone else, but it just occured to me
that this lends itself to inheriting descriptor types:
class ReadOnly(object):
def __get__(self):
raise NotImplementedError("sub-class must override this!")
def __set__(self):
raise AttributeError("read-only attribute")
def __delete__(self):
raise AttributeError("read-only attribute")
class Foo(object):
property myprop(ReadOnly):
def __get__(self):
return ...
