Describe your use case

When I learn nom I had problem on how to create generic parse combinators, I think it should be documented in somewhere.

Describe the solution you'd like

My first suggestion was add an example (#583).

Alternatives, if applicable

I don't think this is the most discoverable place as we are putting it in one example among a bunch and the likelihood of the user finding it is low. Finding an appropriate place within the tutorial would likely be the best approach.

@baoyachi could you explain why you think this could be closed? @guissalustiano had a real need for this as shown in #583 and I'm not seeing the tutorial covering this which is likely the most appropriate place.
