I learned about this a few years ago, but haven't made use of it at all. But I can see how it could be handy. I like using the vector attribute to make gcc generate vector instructions.
Actually this is pretty cool, you can make the same sort of semantics as C++ stack based objects in plain C. With a couple macros you could make it pretty much feature equivalent.
Nah. I think that for many programs the GNU extensions to C provide a better tradeoff in terms of expressiveness vs. added complexity than the truckload of arbitrary features that is C++.
