Dunno - not that impressive. Don't get me wrong, I prefer the
conservative approach of the C std committee to the approach of the C++
one, which yields monsters.
But this looks like relatively minor improvements to me.
What I would like to see in a new C revision:
- Modules;
- Tagged blocks/tagged loop constructs.
The tagged loop thing could look like this:
outer_loop: for (i = 0; i < n; i++)
{
for (j = 0; j < i; j++)
{
...
if (...)
break outer_loop;
}
}
That would be more elegant and easier to statically analyze than goto's.
The syntax could be different, it's just to show the point. In
particular, to avoid confusion with goto labels, it could instead be
something like:
for outer_loop (i = 0; i < n; i++)
...
As to modules, that could be taken from C++20(?) modules, although I
think those are not that great, but that's a start.
