Dear Martin,

Thanks for the clarification and sorry for the noise.

I'm sorry, Georgi, but "of interest" (to some readers) still
does not make this the correct mailing list for the topic,
rather really *does* belong to R-devel instead :

This has been about 

- if an S4 generic for "predict" and similar
  generics should be instantiated in the (base R) 'stats4' package
  (==> change of R, not of a developer's package)

- and about good strategies to define S3 and S4 methods and generics
  (==> general advanced R programming, not directly related get a
       package accepted by CRAN standards)

Followups please on R-devel
((Unfortunately, because of severe spamming of people posting to
  the list, we have delayed archiving the official archives considerably for now;
  to still see the current thread on R-devel, you can use one of
  the *other* archives: ==> https://marc.info/?t=152716935600002&r=1&w=2 ))
