Having this template into object.d seems problematic to me. It is now

to provide any custom GC implementation without messing with Druntime.
Providing a user created GC should be as easy as possible.
It's never going to be easy for anyone to just write their own GC,
especially one that works better than one a lot of people have spent a
lot of time on.
I don't think this is easy. But Different GC have different impact on the
program. For instance, oracle's JVM provide you 4 different GC, that
you can
choose with different configuration parameters.
Those are not user created GCs.
That is exactly what I meant. Metadata about the block shouldn't be
stored
anywhere near the block, because it will behave horribly wrong when
swap come
into play. Metadata must be read and written when GC does its job, but
the block
itself doesn't require it.
I think the point is that it is not up to the compiler how this is done,
but to the GC implementer.
The point was that putting this into object.d isn't, IMO, the best
option to provide such a mecanism.
