Overview

A Stimulus primitive kind: name, plus the Value/Collection classes that back it. Two concrete subclasses distinguish how the primitive behaves when a Hash is passed to the plural parser:

- `Keyed`      — `{a: 1, b: 2}` expands to one value object per pair.
                 Used for values / params / classes / outlets.
- `Positional` — `{...}` is a single-arg descriptor (e.g. Action's
                 `{event:, method:, ...}` short form).
                 Used for controllers / actions / targets.

Instance Method Details

#key ⇒ Object

The primitive’s key in Vident’s attribute namespace. Used both as the parser method name (‘def stimulus_values(…)`) and as the hash key in DSL attrs / component props / `root_element_attributes` — the same Symbol serves all three roles.
