There is an alternative. Ada could pointers fully transparent. So Ptr_1 :=
Ptr_2 would have the meaning of present Ptr_1.all := Ptr_2.all.
Pointer-specific operations would be defined explicitly

procedure Shallow_Copy (Left : in out access-type; Right : access-type);
procedure Assign (Left : in out access-type; Right : target-type);
...
