Python 2.6 has a recently added "with" clause, borrowed from LISP, for associating actions with scopes. This is supported for files and locks, but setting your own object up for "with" requires adding special methods to the object. "with" is less convenient and more limited than RAII, but that's the direction Python is going. This may be in preparation for a move to a real garbage collector.
I do not remember that being stated as part of the rationale for 'with', but just today someone noted that since 'with' replace most uses of deterministic refcount gc, there is not more scope for changing things, at least for builtin and user classes, as opposed to C-extension classes.
