/**
* 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.
