Comment (by nbruin):
Great! thank you. I tried but failed to coerce hg into producing such a
patch. I'm definitely happy with your changes. I'm just not sure that
merging this ticket is actually an improvement. The only `*.pyx` file in
which I was able to find a use of `lazy_attribute` is for `_element_class`
on `Parent`.
On python classes (with a `__dict__`) it will be very hard for the
implementation to be critical, since most usage won't use the
implementation anyway. I can imagine that loading an extension class has
larger overhead than a conventional `*.pyc`, in which case there is
actually a ''penalty'' for cythonizing, and I'm not sure we're getting a
benefit in return.
It's good to have, so that people can use `lazy_attribute` for more time
critical applications. Should we be merging this ticket in anticipation of
such applications arising?
