"This change is a __necessary__ part of evolving D toward being 
memory safe without using a GC"

This is a bold statement, that needs to be addressed with a 
little of explanation of why there are no alternatives.

I think it's not acceptable to suffer such a huge pain, without 
having a clear understanding that there was a deep analysis on 
potential alternative solutions, and an explanation of why they 
are not sufficient for the scope.

Just to be clear, why @nogc is not enough?
