 I understood.

 > Linking n functions to each other requires n*(n-1) different links. If a
 function is moved, if a function is added, that requires much more work.
 Additionally, it possible that somebody *adding* a function may forget to
 update the others, which will not happen if we have an index of function
 at the head of the module.

 Having these links directly in the `SEEALSO` block of the function helps
 the user...and this ranks higher to me than what a developer has to add
 when moving something around (and of course there is `--warn-links` which
 alerts when something is not where it should be). When adding a new
 function it is fine that not all `SEEALSO` blocks contain it; maybe only
 the close related ones. In `sage.misc.mrange` there are just a few
 functions and all those should IMHO be linked. In larger files I would
 *not* link all in all, but only build "cliques" of very related functions
 (but this depends on the functions, of course).
