Update soak implementation when optional chaining becomes stable
See original GitHub issueCurrently there’s a prototype implementation (--use-optional-chaining) mapping ?. syntax to JS optional chaining ( https://github.com/tc39/proposal-optional-chaining ), but upgrading Babel broke it because the latest spec does not allow soaked assignments, soaked new, and possibly other forms. Once the syntax and semantics settle down, it would be good to revisit. For now, I’m disabling the failing tests from the initial prototype.
