RE: [Zope3-dev] Proxy and __slots__

2005-08-29 Thread Garrett Smith
I ended up using 'type' to create a new proxy with a dynamically created 
__slots__. I haven't run into any weirdness with that approach, so far :)

I'd like to create a proxy where __slots__ is determined (or appended to) when 
the proxy is constructed. E.g.



foo = Foo()
bar = SomeProxy(foo, 'baz')
bar.baz = 123
hasattr(foo, 'baz')


False


hasattr(bar, 'baz')


True

Is it possible to do this?


No, at least not using the standard __slot__ mechanism.
