Thank you, but, well... for such small changes -- that would be
quite a bit of (human, i.e. R-core) overhead, but of course is
generally a good possibility  (but here, wait! .. and read on : )

Actually -- this now gets more  "R-devel" - appropriate --
I notice that there are quite a few  error("..." .. )
and also  warning("..." ..) calls in
src/main/altclasses.c *and* in
src/main/altrep.c        and *none* of them asks for translation;

While this could be for historical reasons (code originally much
by Gabe Becker from outside R-core *and* at first just in a
separate branch before being merged in to the main (r-devel)
branch.
OTOH: There may be good reasons for translations lookup being
brittle in case of altrep error messages .. and hence left off
purposely?
