I'm more extreme in this camp -- I use auto everywhere. Why? because at 
some point, I may change some type somewhere (oops, I should have wrote 
size_t instead of uint), and then I would have to go through and change 
all the places I put the concrete type if I hadn't used auto.

While using functions, I also can use auto and not have to worry about 
the type. I know kind of what it is (integer type, string type, range 
type, etc), and not care what the exact type is.
