The theme of an old Python conference (the only one I've had the pleasure of attending) was "Life is better without braces." I just lost about an hour of my life trying to clean up some Javascript code (which I rarely touch) to eliminate an image rollover problem that occurs on a site that we're replacing. Everything looked right. But time after time after time, the code wasn't running. Finally, I realized the problem: I had lost a closing brace on a function definition. I put the brace back, everything now works as it always should have.
