Not thinking about indentation is fine. It would also be fine if you never 
thought about type identifiers. But using _Type doesn't eliminate thinking about 
type identifiers, just thinking about /good/ type identifiers (the most 
important kind of thinking).

I disagree very strongly with the single-letter idea. Although I have seen 
plenty of single-letter parameter names, I have never seen a case where it was 
appropriate, or where a little thought couldn't come up with good names.
