digitalmars.D.announce - automem v0.3.5 - now with more vector (like std::vector, not Physics)!

I needed something like a std::vector that can be  nogc so I 
wrote it. I wondered whether or not to put it in a collections 
package or not, then punted on the decision and just stuck it in 
automem. Anyway, code:


     // *no* GC allocations below if theAllocator is set to an 
allocator that
     // never allocates on the GC heap

     import automem.vector;  // there's an `array` alias too
     auto v = vector(0, 1, 2);
     v ~= 3;
     v ~= only(4, 5);
     assert(v[] == [0, 1, 2, 3, 4, 5]);


If you want the  nogc compile-time guarantee, specify an 
allocator:

     ()  nogc {
         auto v = vector!Mallocator(0, 1, 2, 3);
         v ~= only(4, 5, 6);
         // etc.
     }();


Enjoy (hopefully)!

Official bindings to std::vector will soon be added by manu. (I 
think)

Sorry for asking here.

Shouldn't this code work?

import automem;

struct X {
     int i;
}
struct Y {
     RefCounted!X x; // fails
     //X x;          // ok
}
void main()
{
     Y y1;
     Y y2;
     y2 = y1;
}

This really should have been a github issue, but thanks for 
posting this anyway. I just fixed it.
