https://github.com/tc39/ecma262/pull/988 gained concensus during the september 2017 TC39 meetings. This moves the load of the "next" method to the very beginning of the iteration protocol, rather than during each iteration step. This impacts: - yield* - for-of loops - spread arguments - array spreads In the v8 implementation, this also affects async iteration versions of these things (the sole exception being the Async-From-Sync iterator, which requires a few more changes to work with this, likely done in a followup patch). This change introduces a new AST node, ResolvedProperty, which can be used as a callee by Call nodes to produce the same bytecode as Property calls, without observably re-loading the property. This is used in several AST-desugarings involving the iteration protocol.
