Unable to use method named as attributes( ) in a model.

Introduction

Unable to use method/property named as attributes( ) in a Model.

Issue Description

export default function relationshipAttributeSet(bookshelf) {
	const RelationshipAttributeSet = bookshelf.Model.extend({
		attributes() {
			return this.belongsToMany(
				'RelationshipAttribute', 'bookbrainz.relationship_attribute_set__relationship_attribute',
				'set_id', 'attribute_id'
			);
		},
		format: camelToSnake,
		idAttribute: 'id',
		parse: snakeToCamel,
		tableName: 'bookbrainz.relationship_attribute_set'
	});

	return bookshelf.model('RelationshipAttributeSet', RelationshipAttributeSet);
}

Consider the above Model. It has a method attributes( ). When I try to use this method it throws Error: attributes is not defined on the model. If I change the method name from attributes( ) to any other name it works fine.

Expected behaviour

Should not throw any error If a method is named as attributes( )

Actual behaviour

Throws Error: attributes is not defined on the model
Cannot use method defined as attributes( ) in a Model.
