The fact that my "catch" block is in a different scope than the "try" block. If I really needed to do it, I could subclass "exception" and dump my variables there. But usually I'm just debugging something stupid so it's easier to put in "print" statements.

I've even put in a "macro" that gives me a "print" statement with a long string of "+" afterword so I can quickly spot them in my code and delete them (but don't tell anybody, 'cuz that's just plain wrong...).
