I plan to do some subversion administration
tomorrow; in order to be able to roll back changes,
I have to disable write access during these
changes.
The outage shouldn't last longer than one hour;
most likely, it will be much faster.

i'd guess this has been brought up before, but i'm not aware of it.
anyway --
by what i've gathered, today's dir() "collects" the attributes of the
object from __dict__, __methods__, __members__, and ultimately
__class__. also, if i understood correctly, __methods__ and
__members__ are deprecated.

So.. are we only thinking about implementing this outer scope
assignment because
there's lots of talk about it on the list, or are there actually use
