/**
* Linear acceptor that can be composed into a chain.
*
* The acceptor exposes a method for setting a value of the
* {@link #setDefaultNext(Stage) next acceptor} in the chain that
* should be returned from the chain by default.
*
* The typical use case for implementing the acceptor is a logic that usually
* needs to perform some logic, but unlike an {@link Stage.Builder#to(Function)}
* acceptor created from a function} it also needs to be able to decide to override
* the default next acceptor and return a different acceptor, effectively branching
* away from the original linear acceptor chain. This technique can be e.g. used
* to break the accepting chain by returning a custom {@link Inflecting inflecting}
* acceptor, etc.
