Hi, all.

I've had a couple occasions in the last 2-3 days where people didn't
know you can do step-wise debugging of JavaScript.  So just in case
others are suffering in Y.log pain, I'll point out the debugger
statement, which works in all the developer/js consoles like Firebug
and Chromium's inspector.

Add "debugger;" anywhere to trigger the debug console:

function foo() {
    debugger;
    doingSomething(bar);
}

You can also go to the script tab in said tools and click a line
number and reload the page to trigger step debugging on the fly.

Hope that helps!

Cheers,
deryck
