Comment (by SimonKing):
Putting a print statement into the lazy attribute
`_set_of_super_categories`, the command
{{{
N=20; matrix(QQ,N,N,srange(N*N)).echelon_form()
}}}
actually prints ''nothing''. Hence, all the work for the subcategory test
seems to be done in the `_subcategory_hook_` methods. So, we should focus
on them.
