Linear acceptor that can be composed into a chain. The acceptor exposes a method for setting a value of the 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 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 inflecting acceptor, etc.
