Design doc: bit.ly/v8-repl-mode This CL allows the usage of 'await' without wrapping code in an async function when using REPL mode in global evaluate. REPL mode evaluate is changed to *always* return a Promise. The resolve value of the promise is the completion value of the REPL script. The implementation is based on two existing mechanisms: - Similar to async functions, the content of a REPL script is enclosed in a synthetic 'try' block. Any thrown error is used to reject the Promise of the REPL script. - The content of the synthetic 'try' block is also re-written the same way a normal script is. This is, artificial assignments to a ".result" variable are inserted to simulate a completion value. The difference for REPL scripts is, that ".result" is used to resolve the Promise of the REPL script. - ".result" is not returned directly but wrapped in an object literal: "{ .repl_result: .result}". This is done to prevent resolved promises from being chained and resolved prematurely: > Promse.resolve(42); should evaluate to a promise, not 42.
