eval does not execute within the proper context when hooked

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Enable win.eval hook
2. Execute evel within the context of a function, not a window, and reference 
variables that are only valid within the function context

What is the expected output? What do you see instead?

eval command should work

What version of the product are you using? On what operating system?

eval is executed within the context of the window

Please provide any additional information below.

function x() {
  var y = 1;

  try {
    eval("y++");
  } catch(e) {}
}
var z = new x();

Not sure if the try/catch block or function creation matters.
