Just to mention in passing - there's a related principle that converting a block to a closure shouldn't change its semantics. This obviously doesn't fully work because of return/break/continue; that said, if a block without such flow control constructs is wrapped into a closure, you'd expect it to just work. It doesn't, because to work it would have to be a once-called-stack-allocated lambda, which Rust doesn't have (I don't get the reason for that either :-)
If you decompose into a lambda plus the tupled set of upvars which it's moving out of, then this respects TCP.
