Wow, you like to live on the edge!  :)

Unless I'm vastly mistaken, the code is compiled into exactly the same 
assembly commands as
In other words, there's no computational benefit to writing that as a 
single statement.

I encountered this quote a week ago, and it's already become my favorite 
saying:  "Debugging is twice as hard as writing the code in the first 
place. Therefore, if you write the code as cleverly as possible, you 
are, by definition, not smart enough to debug it." - Brian W. Kernighan

I'm all for using ++ and --, but only if they're the only thing 
happening on that line.  If anything else is happening, I need to 
actually think about what's happening, and that's dangerous if you're 
trying to write maintainable code.  :)
