Post #2227729

@oli@hachyderm.io @Mara@hachyderm.io it's not a closure since it can contain control flow, and also likely do things that borrow checker wouldn't like a closure doing. It was desugared to explicitly query the LHS whether or not to short circuit, and run the RHS if not. https://internals.rust-lang.org/t/pre-rfc-overload-short-curcuits/10460/29
