I use a lot of private types, not visibly of an access type, but 
privately defined as an access to a type defined in the body of the 
package. I want to hide, to some extent, the fact that the type is 
implemented as an access type, so I don't use _Ref on the object 
identifiers. Nearly all uses of identifiers for such objects occur 
as formal or actual parameters; the only reason that I use _Ref on 
the type-name, instead of _T, is to explain why the parameter mode 
is nearly always "in", although the parameter may be modified:

    procedure Foo (Object : in Object_Ref) ...

Using _Ref on the object identifiers would reduce readability in my 
opinion -- the many _Refs would clutter the statements, and not 
only the declarations. I treat the _Ref suffix as reserved for 
access types.
