@akarnokd Do you want to extend this branch and merge the various PRs in to it that belong here?

If you don't like the name go ahead and propose something, I couldn't think of anything better but only spent a couple minutes on this.

I want something generic enough to cover the various utilities. At the same time I feel this name may be too broad as these utilities may not apply at all to other JVM languages, but that's probably fine as that's why it's a contrib module.

RxJava-pull-requests #613 FAILURE
Looks like there's a problem with this pull request

Thanks @benjchristensen the name is okay. I'll update and resubmit the relevant PRs. Should Observable.from(Future) and its overloads from before be moved into this module?

[benjchristensen]

Leave Observable.from(Future) in Observable for now. We'll need to do a deprecation process on those if we remove them.

I'm closing this PR as you will take my branch and re-submit a new one.

[akarnokd]

I'm sorry I don't quite understand. I check out your branch then, once all ops are added, I submit a PR against RXJava/master?

[benjchristensen]

Yes.
