Merge pull request to a different branch than default, in Github
... with Daniel Pittman's solution, however I would treat those merges as "no fast forward", that is, changing step number 3 for:
git checkout ${target_branch} && git merge --no-ff ${remote}/${branch}
By using --no-ff, the history will be easier to read. It will clearly say that $n commits cam...

Limit a stream by a predicate
...te to the JDK implementation (via MethodHandle.invokeExact which is really fast). When running under JDK-8, the "polyfill" implementation will be used. So using my library the problem can be solved like this:
IntStreamEx.iterate(1, n -> n + 1)
.takeWhile(n -> n < 10)

If you need a data structure that supports both fast membership tests and preservation of insertion order, you can use the keys of a Python dictionary, which starting from Python 3.7 is guaranteed to preserve the insertion order:
