Overview

A State instance is kept per DSL client, which usually is a subclass of Path, Railway, etc. State doesn’t have any immutable features - all write operations to it must guarantee they only replace instance variables.

DISCUSS: why do we have this structure? It doesn’t cover “immutable copying”, that has to be done by its clients.

also, copy with to_h

#initialize(normalizers:, initial_sequence:, fields: {}.freeze, **normalizer_options) ⇒ State

remembers how to call normalizers (e.g. track_color), TaskBuilder remembers sequence
