1. Change the AST node type CallNew to be a subclass of Expression rather than Call. It's not really a call but it just happens to have the same fields. 2. Change our error reporting for invalid left-hand sides in for-in statements, pre- and postfix count expressions, and assignments. Before we signaled a syntax error at compile time *unless* the LHS was a function call or 'new' expression, in which case we signaled a reference error at runtime. Now we signal a reference error at runtime in all cases. This matches the JSC behavior in Safari 4.
