Yes, and you can also always obtain a far pointer from a near one. But there's 
always a cost, otherwise there'd be no point to having near pointers.

If C++/CLI nailed it, why has C++ in general not adopted it? Why has nobody 
create a C compiler, but with GC? What is the point of Rust if GC is the answer?
