Suffix _T for types found good

I just want to offer my experience on the old issue of adding a suffix
_T to all type names.

In my experience it is good.

In a large (50KLOC) industrial experience of analysing Ada 95 source
(written by others) this convention clearly helped understanding the
source and writing test cases. This was a team work.

I started using the convention in the personal process also, and also
experienced improvement. In the personal process, I particularly like
that:

(1) I don't have to think up "good" type names that sometimes simply
do not exist; too often it is very difficult or impossible to come up
with a good pattern of names for the type, the object, the array,
etc.; with _T at least one term is removed from the equation

(2) I can promptly write things like

Index : Index_T;
procedure Proc (Index : Index_T);
etc.

For access types I have been writing _Ptr_T but I'm not 100% happy.

Regarding "_T" vs. "_Type" I am convinced the former is better but I
have to leave the advocacy for later. Or for others ;-)
