Comment(by SimonKing):
Concerning lazy attributes: I wonder whether one could add a method
`rename(name)` to a lazy attribute. That method would return a copy of the
original lazy attribute, but with a new name.
Then, the example above would become
{{{
sage: class Foo(object):
....: @lazy_attribute
....: def _bar(self):
....: return 5
....: bar = _bar.rename("bar")
....:
sage: f = Foo
sage: f.bar.__name__
'bar'
}}}
