:= isn't that bad an idea. Heck, adding it to C17 could work -- C syntax is
not set in stone, just like it imported // comments from C++.

I'm annoyed that C disallows:
    if (foo)
        bar, break;
On the other hand, for most statements this works:
    return fprintf(stderr, "meow\n"), 1;
or even (in a void function)
    return fprintf(stderr, "meow\n"), (void)0;
