But then lists are not the “elements which do not have readable print 
syntax”, while we asked you example of such elements.

Yes, you need to traverse the list, but to print a list you traverse it 
anyway.  The idea of an “extensible print” is that during that recursive 
traversing that print already does, if it encounters a “object that it 
doesn’t know how to print”, we teach it to use a function that knows how 
to print it in a such way that it can be read again.
