If the use of block-statements becomes common for certain tasks such as opening files, it seems to me that people are going to encounter their use around about the same time they encounter for-statements. We need *something* to tell these people to enable them to understand the code they're reading.
Maybe it would be sufficient just to explain the meanings of those particular uses, and leave the full general explanation as an advanced topic.
Right. The block statement is a bit like a chameleon: it adapts its meaning to the generator you supply. (Or maybe it's like a sewer: what you get out of it depends on what you put into it. :-) -- --Guido van Rossum (home page: http://www.python.org/~guido/)
