Discussion: Whether to use `auto` for iterators

[stephengtuggy]

          I'm fine with type inference where it is trivial. Example from other languages is something like

let someString = String('blah blah')

However, I'm less comfortable with replacing std::list::iterator with auto. I prefer to clearly see my C++ abominations.
