Personally, I never discussed with anybody what exactly using the word SFINAE
in a subject means. I only fix bugs ;) Anyway, in practice, as far as this
issue is concerned, it should be clear by now that, as I suspected, it doesn't
have much to do with SFINAE, can be easily reproduced in all sorts of contexts,
with very simple testcases.
