Included in:
CommandInterpreter, EntityInterpreter, PortOperationInterpreter

Overview

What every stepwise interpreter shares: the traced step, and the coercion of a command's declared arguments. Two copies of each lived in CommandInterpreter and EntityInterpreter, where they could only ever drift.

Class Method Details

.included(interpreter) ⇒ Object

Each including interpreter gets its own trace — set by a spec to observe dispatch order (Vocabulary::AggregateDispatchOrder and Vocabulary::EntityDispatchOrder in language/bluebook/vocabulary.bluebook); nil in production, always — one array push and a nil check per step is the entire cost of leaving this in.
