that longstanding idiom implies people seeing a warning and blindly applying it, without thinking about whether there is a real bug
Sure, but now with Gnulib, ignore_value (E) is the new idiom for (void) (E). A careless developer blindly applying ignore_value now is like a careless developer blindly applying a void cast in the good old days.Nothing has changed, really.
If GCC changes again in this area, I hope Gnulib's ignore_value continues to work. It would be a pain to have yet another musical-chairs period during which there is needless confusion.
