Integrate friendly tips from Tor colleagues to make (or not) 4.5 alpha 3;
This includes removal of overloaded (but unused) methods, and addition of
a overlooked call to DataStruct::SetData(nsISupports, uint32_t, bool.)
1 // Constant folding doesn't affect strict delete either.
2 // In particular, it doesn't affect whether |delete x| is a strict error.
4 load(libdir + "asserts.js");
6 (function (x) {
7 "use strict";
9 // These senseless delete-expressions are legal even in strict mode.
10 // Per ES5.1 11.4.1 step 2, each one does nothing and returns true.
11 assertEq(delete (1 ? x : x), true);
12 assertEq(delete (0 || x), true);
13 assertEq(delete (1 && x), true);
15 // Plain `delete x` is a SyntaxError though.
16 assertThrowsInstanceOf(() => eval('delete x'), SyntaxError);
17 assertThrowsInstanceOf(() => Function('"use strict"; delete x'), SyntaxError);
18 }());
