1 // The objects on the environment chain are all Debugger.Environment objects.
2 // The environment chain ends in null.
4 var g = newGlobal()
5 g.eval("function f(a) { return function (b) { return function (c) { h(); return a + b + c; }; }; }");
6 var dbg = Debugger(g);
7 var hits = 0;
8 g.h = function () {
9 var n = 0;

11 n++;
12 assertEq(env instanceof Debugger.Environment, true);
13 }
14 assertEq(n >= 4, true);
15 hits++;
16 };
17 assertEq(g.f(5)(7)(9), 21);
18 assertEq(hits, 1);
