Nearly always, when starting a GenServer (or Agent or ...) from a process
(so not inside a supervision tree),
the process doing the starting does not have a reasonable behaviour to
continue in the case that the starting fails
(other than to itself crash).
GenServer.start and GenServer.start_link (and Agent.start,
Agent.start_link, etc.) return an `{:ok, pid}` tuple. (or `{:error, info}`)
I am wondering if it would be possible to introduce GenServer.start! and
GenServer.start_link! (and item for Agent, ...)
that return just the `pid` (and crash on failure).
The main advantage of this is that start and start_link cannot be
incorporated into pipelines, as they return a tuple, whereas
the bang-versions would.
Would this be a good idea, or has a conscious choice been made to *not*
include bang-versions of GenServer.start and GenServer.start_link (and
variants)?
