C99 or C11?

Serious topic. No mention of C89 as it is objectively inferior to C99.

I prefer C95, which I feel is actually the height of C standards, although often overlooked because it follows the breakout success of C90 (C89 to those of you who follow the American releases). The ISO was still in their breakout phase during '95, and after the legendary tour of '94 (I was at Geneva, Feb 23) they started to experiment with more progressive themes. This was a bit too fast-paced of a change for most of the old line fans, who just wanted to hear Ritchie play union{ int d; char c;}; , so real gems like the %:%: digraph and wint_t were ignored. Even more, prototypes like int wcsncmp (const wchar_t *, const wchar_t *, size_t) are most often attributed to the later C99, which proved too divisive for most compilers at the time, and the fact that this is still cited as a point in C99's favor should only be taken as a comment on the ages of the fans. As for C99 itself, people tell me I just don't understand stdbool.h, but I've read through it dozens of times, and it doesn't sound fresh at all, more like an experimental failure that caught on for the wrong reasons and then couldn't be forgotten. I can still appreciate the good points of C99, but compared to C95, it just doesn't hold up.
