Hm, I don't know directly how to get the name of a variable. I'd  
hoped there was a private method (var3.__<something>__), but looks  
like there isn't it.

Perhaps you can do something with a dictionary, eval and/or map? Not  
sure how that would work out, you'll have to play around a bit to get  
it working.

But I'm not really sure why you'd want to pass the variable names to  
a function; in the end, you're going to use the actual values anyway,  
not their names, right?
