Except the return type that you wrote in that case tells you
almost everything you can do with that value. If you specify
the return type of a function as `auto`, it tells you nothing.
The Java equivalent would be to return Object.
My point was about implementing an interface you can rely on,
regardless of what auto returns, eg:
auto name = user.name;
user could be anything, but it still has the field / property
'name'.
