Let's translate that to non-decorator Python:
"""
class A(object):
def __init__(self):
self.not_here = 1
def _(self):
return self.__not_here
not_here = property(_)
del _
def _(self, val):
self.__not_here = val
not_here = not_here.setter(_)
del _
"""
@not_here.setter exists because not_here.setter exists. not_here exists
since we set it (when the getter/property was set).

PS: are you sure the lambda self: self.__foo() trick works, with
subclasses or otherwise? I haven't tested it, and I'm not saying it
doesn't, but I have a feeling double-underscore name mangling might be a
problem somewhere down the line?
