name

let's give our terms names. it can be a static string this time.

/**
 * @typedef {object} Term
 * ...
 * @property {string} name
 */

terms are ANONYMOUS by default.

Term.Default = {
	//...
	name: "anonymous term"
}

string terms are named after their string.

Term.string = (string) => ({
	//...
	name: `"${string}"`
})

we can update the default translate method to use the name in error MESSAGES.

Term.Default = {
	//...
	translate(text) {
		const bites = this.bite(text)
		if (bites.length === 0) {
			throw new Error(`Expected ${this.name} but found '${text}'!`)
		}
		return bites.join("")
	}
})

here it is in action.
