digitalmars.D.learn - Explicit Class Instance Allocation

reply "Mike" <none none.com> writes:
In this article (http://dlang.org/memory.html) there is an 
example showing how one could explicitly allocate and deallocate 
an object.  However, the article seems to be sorely neglected and 
out of date ('delete' is deprecated, right?).  Could someone 
modify the example below using current best practices.

import std.c.stdlib;
import core.exception;
import core.memory : GC;

class Foo
{
     new(size_t sz)
     {
         void* p;

         p = std.c.stdlib.malloc(sz);

         if (!p)
             throw new OutOfMemoryError();

         GC.addRange(p, sz);
         return p;
     }

     delete(void* p)
     {
         if (p)
         {
             GC.removeRange(p);
             std.c.stdlib.free(p);
         }
     }
}

Thanks,
Mike

Also that usage of new() is deprecated.

It's mentioned here: http://dlang.org/class.html#allocators.

Perhaps a bugreport or even a pull request is in order?
