C99 object literals are also fantastic. I feel very constrained when I have to use strict C89. Meanwhile, in terms of C11 [update: actually also from C99] I actually wrote a function with a signature like void func(int arg[static 3]); but later removed it because (a) the generated code was the same, and (b) rather than increasing clarity and self-documentation, it caused confusion; even when you're familiar with the feature, it never stops looking like a syntax error.
