[erlang-questions] gen_server:init(Args) -> {stop, {normal, Reply}}

Hello Aleksey,

You can gracefully stop a gen_server on `init` by wrapping the reason for
stopping (or a "reply") in a `{shutdown, _}` tuple, e.g.:

    init(_) ->
        {stop, {shutdown, Reason}}.

This way it won't be interpreted as a crash but still be returned to
whomever called `gen_server:start_link`.
