        if (this.patterns) {
            return sparql `WHERE {
${this.patterns}
}`;
        }
        if (required) {
            return sparql `WHERE {}`;
        }
        return sparql ``;
    },
    WHERE(strings, ...values) {
        return {
            ...this,
            patterns: concat(this.patterns, strings, values),
