No errors\n will be recorded nor thrown in this scope.\n\n- MaybeArrowParameterDeclaration\n A scope that represents ambiguous arrow head e.g. `(x)`. Errors will be recorded\n alongside parent scopes and thrown when `ExpressionScopeHandler#validateAsPattern`\n is called.\n\n- MaybeAsyncArrowParameterDeclaration\n A scope that represents ambiguous async arrow head e.g. `async(x)`. Errors will\n be recorded alongside parent scopes and thrown when\n `ExpressionScopeHandler#validateAsPattern` is called.\n\n- ParameterDeclaration\n A scope that represents unambiguous function parameters `function(x)`. Errors\n recorded in this scope will be thrown immediately. No errors will be recorded in\n this scope.\n\n// @see {@link https://docs.google.com/document/d/1FAvEp9EUK-G8kHfDIEo_385Hs2SUBCYbJ5H-NnLvq8M|V8 Expression Scope design docs}\n */\n\nconst kExpression = 0,\n kMaybeArrowParameterDeclaration = 1,\n kMaybeAsyncArrowParameterDeclaration = 2,\n kParameterDeclaration = 3;\n\ntype ExpressionScopeType = 0 | 1 | 2 | 3;\n\nclass ExpressionScope {\n type: ExpressionScopeType;\n\n constructor(type: ExpressionScopeType = kExpression) {\n this.type = type;\n }\n\n canBeArrowParameterDeclaration(): this is ArrowHeadParsingScope {\n return (\n this.type === kMaybeAsyncArrowParameterDeclaration ||\n this.type === kMaybeArrowParameterDeclaration\n );\n }\n\n isCertainlyParameterDeclaration() {\n return this.type === kParameterDeclaration;\n }\n}\n\ntype ArrowHeadParsingParameterInitializerError =\n | typeof Errors.AwaitExpressionFormalParameter\n | typeof Errors.YieldInParameter;\ntype ArrowHeadParsingDeclarationError =\n | ArrowHeadParsingParameterInitializerError\n | typeof Errors.InvalidParenthesizedAssignment\n | typeof Errors.AwaitBindingIdentifier;\n\nclass ArrowHeadParsingScope extends ExpressionScope {\n declarationErrors: Map<number, [ParseErrorConstructor<{}>, Position]> =\n new Map();\n constructor(type: 1 | 2) {\
