FWIW - my personal rule is to never use auto.

The type conveys information. I think hiding information is a bad idea
in general. (note before anyone complains: hiding information is not
the same as abstracting and interface).

auto is hack to permit one to work around some unfortunate situation
which might occur while engaged in Template MetaProgramming. I haven't
kept track, but I've found it necessary in probably less than 10 cases
over the years.

(Almost) Never use auto!)
