I was reading through old messages in the list and came up against an idea that I thought might be of some value: "Wouldn't it be a good idea if one could "rewind" an iterator?" Not stated in precisely those terms, perhaps, but that's the way I read it.
I appreciate that one could use a sequence rather than an iterator, and that I don't understand the implementation issues. (They don't look large, but what to I know?) But would it be a good idea to have a rewind method for iterators? I tend to think of them as mag tapes, and I was always wanting to rewind those. Or skip to file n. (Well, that probably doesn't have any relevance to the usage of iterators.) OTOH, if this is a bother, it's almost always quite easy to create a new iterator, it just feels less efficient. Still, I would use this much more often that I would use reversed (which I've never wanted to use). -- http://mail.python.org/mailman/listinfo/python-list
