BTW: (add-function <foo> (symbol-function <bar>) <toto>) is generally
better written as (advice-add <bar> <foo> <toto>).  The difference is
that advice-add will work even if <bar> is not yet defined (i.e. no
need for eval-after-load), and it will work if <bar> is autoloaded, and if
it's a macro, etc...
