Comment:

I suggest to base a thematic tutorial on this worksheet.

It covers base classes for parents and elements, category framework for parents and elements, uniqueness of parents, coercion maps, construction functors, and test suites.

The didactical approach is to explain the theory and illustrate each theoretical bit by showing how it can be implemented. Step by step, one obtains an alternative implementation of fraction fields.

There are also several texts in the combinat branch, and I suggest to add these as well. The style of these texts is very different from the style of my worksheet, and I hope that the user will benefit from diversity.

     5Note that it may relate with #8821, which is about adding a section on coercion (but not categories) in the guided tour.
