Comment (by xushiwei):

 [45190]:

 1. Update GC Allocator specification. The following is minimum
 specification for GC Allocator:

 {{{
 typedef void (*DestructorType)(void* data);

 concept GCAllocator
 {
     // Allocate memory without given a cleanup function
     void* allocate(size_t cb);

     // Allocate unmanaged memory with a cleanup function
     void* unmanaged_alloc(size_t cb, DestructorType fn);

     // Commit unmanaged memory to be managed.
     void* manage(void* p, destructor_t fn);

     // Deprecated: allocate memory with a cleanup function
     void* allocate(size_t cb, DestructorType fn) {
        return manage(unmanaged_alloc(cb, fn), fn);
     }

     // Cleanup and deallocate all allocated memory by this GC Allocator
     void clear();

     // Swap two GCAllocator instances
     void swap(GCAllocator& o);
 };
 }}}
