First off, I want to thank you for actually engaging in a conversation, rather than simply writing me off as whiney and pedantic. I posted about something that I wanted to discuss, not just whine about. :-)

That it doesn't go out of scope doesn't make it less of a closure, but its closureness doesn't get used.

Indeed, that's true. I suppose I shouldn't try to fight against the technical definition. Rather than saying it's not a closure, I should have said it's not very useful to talk about its closure-ness.

However, it is a closure and it's not wrong calling it one.

Ok, fair enough. I officially change my position on the matter. Again, thank you for responding. I hope our friend SpanishInquisition is not too upset about the matter to read what I've written here, so he won't think I'm a completely horrible person.
