First, I like this a lot. I think applying it to operators as well is definitely a good thing. I don't feel strongly about these closures needing to copy the bound values. If you consider them a syntax for currying, one would expect them to copy, but you could also look at them as a shorthand for block/lambda syntax, in which case not copying makes perfect sense. The difference might be moot, actually, since fn@ will copy anyway, and blocks don't escape the call that uses them mutation of the closed over variables will rarely be an issue.
