I suggest a "built in" raw pointer type and a managed pointer 
type. The raw pointer type should not be used in safe D 
programming because safe D relies on garbage collection. The 
entire druntime/phobos should be changed in order to use the 
managed pointers instead for any raw pointers (unless special 
cases). The functionality of the managed pointer type should be 
able to be completely customized in order to support all sorts of 
different GC algorithms.
