Your implementation seems particularly broken. You do not return anything
from `name()`, hereby removing name as an attribute (or: replacing it
with its return value -- None). You should return ``property(**locals())
`` (or ``property(fget=fget, fset=fset, ...)``, whatever you like).
I'm going to point out a few other mistakes first:

Typo here: __init__

It should be `val`, not `name`, huh? And, as mentioned above, the return
value is missing.

A fixed implementation could be something along these lines::
>>> class Toto(object):
... def __init__(self, name):
... self.name = name
... @apply
... def name():
... def fget(self):
... print "getting %s.name" % self
... return self._name
... def fset(self, val):
... print "setting %s.name to %s" % (self, val)
... self._name = val
... return property(**locals())
... def say_hello(self):
... print "Hello, my name is %s" % self.name
...
>>> t = Toto("bruno")
setting <__main__.Toto object at 0xb792f66c>.name to bruno
>>> t.say_hello()
getting <__main__.Toto object at 0xb792f66c>.name
Hello, my name is bruno
>>> t.name
getting <__main__.Toto object at 0xb792f66c>.name
'bruno'
>>> t.name = "jon"
setting <__main__.Toto object at 0xb792f66c>.name to jon
>>> t.say_hello()
getting <__main__.Toto object at 0xb792f66c>.name
Hello, my name is jon
