Test that this no longer happens. // // The code generated for unary + assumes that we are not in a spilled // scope. var o = new Object(); // The code for the iterated-over object in for-in used to be emitted // in a spilled scope: for (x in +o) { } // Emitting code for the left hand side of a for-in. for (a[+o] in o) {} // The receiver in an obj[index](1, 2, 3) call: try { o[+o](1,2,3) } catch(e) { // It's OK as long as it does not hit an assert. }
