/**
 * Takes a predicate and a `Filterable`, and returns a new filterable of the
 * same type containing the members of the given filterable which satisfy the
 * given predicate. Filterable objects include plain objects or any object
 * that has a filter method such as `Array`.
 *
 * Dispatches to the `filter` method of the second argument, if present.
 *
 * Acts as a transducer if a transformer is given in list position.
 *
 * @func
 * @memberOf R
 * @since v0.1.0
 * @category List
 * @sig Filterable f => (a -> Boolean) -> f a -> f a
 * @param {Function} pred
 * @param {Array} filterable
 * @return {Array} Filterable
 * @see R.reject, R.transduce, R.addIndex
 * @example

 *      const isEven = n => n % 2 === 0;

 *      R.filter(isEven, [1, 2, 3, 4]); //=> [2, 4]
