Could you please also fix the other things mentioned in#2568 ? And add thepull request format to the pr description?

@wouterj PR format added. For thereduce function, there's nothing to do AFAICT, unless you want me to make the example more complex?

you're right actually, I never did a good look into that example. I'm 👍 for this, thank you for working on it!

One thing though: We can/should add a vesionadded directive mentioning the change. Something like:

..versionadded::2.3    The node argument is a ``Crawler`` instance as of Symfony 2.3.    In prior versions, it was a ``DOMElement`` instance.

Do you want me to do it?

If you can do it: Yes! Otherwise I'll create a PR

Any news on this topic?

Hi Julien!

Thanks for the nice PR here! I've patched this into the 2.3 branch at sha:ed0920e. You'll notice that some of the changes are missing, only because they have already been done in other PR's. I also added theversionadded and a type-hint at sha:a15a9d5

Thanks!
