Does IE9 support console.log, and is it a real function?

Question

In which circumstances is window.console.log defined in Internet Explorer 9?

Even when window.console.log is defined, window.console.

Answer 1

After reading the article from Marc Cliament's comment above, I've now changed my all-purpose cross-browser console.log function to look like this:

function log()
{
    "use strict";

    if (typeof(console) !== "undefined" && console.log !== undefined)
    {
        try
        {
            console.log.apply(console, arguments);
        }
        catch (e)
        {
            var log = Function.prototype.bind.call(console.log, console);
            log.apply(console, arguments);
        }
    }
}
