Support Observable.from(array_of_primitives)

It seems that it is currently impossible to create an Observable from an array of primitives, e.g.:

char[] chars = "some string".toCharArray();
Observable.from(chars); //does not compile

Is this a conscious decision?

[akarnokd]

char[] chars = "string".toCharArray();

Observable.range(0, chars.length).map(i -> chars[i]).subscribe(...)

Another way to do it: Observable.fromArray("string".split("")).map(s -> s.charAt(0)).subscribe(...)
