So I'm curious, what's the consensus on auto?
My rule, is when I can't be bothered typing it all out, or can't
be bothered working out what it is I'm actually meant to type,
then I use auto (or var).
i.e. I use it as a time saver, and that's all.
The exception to that rule, is when it's important to the person
writing/reading that code, to known what type is being used (and
that's a rather subjective decision). In most cases, the type
declaration is for other reasons (i.e not human consumption).
btw. In 1969, John C. Reynolds published his paper/specification
on GEDANKEN - a typeless programming language, and type
declaration was simply not permitted.
(Gedanken is German for thought experiment, more or less)

I wonder whether this is where languages will eventually end up
again, in the future some time.
