Draft: RFC: reference: Experimental cross-reference to the tutorial
Providing cross-references to longer examples seems like it might be useful, but I'm not sure about this. The tutorial and reference have a different structure (which is appropriate) but that means that reference sections don't correspond neatly to parts of the tutorial. Also, the tutorial's section headings are less formal, which will make these kind of links fragile.
Apropos #8 (closed), although I think I'd be willing to call #8 (closed) done without these kind of references into the tutorial.
