`.toArray()` for all generators

It would be nice from a readability point of view if `iteratable.toArray()` could always be used as a substitute for `Array.from(iteratable)`.  Is there a way that could be neatly achieved?  It would also be nice if methods like `.map` and `.filter` existed on iteratables.  C# does this via the concept of extension methods, but I wonder whether something similar could be achieved here, at least in the case of built in iteratables?
