<<Because infix operators don't read as nice when fully qualified, of
course...
 
  Some_Stack_Type.Push(Value => A_Thing.Object, Onto => A_Stack.Object);
-- nice
 
  if Some_Stack_Type.Is_Empty(A_Stack.Object) ... -- OK
 
  if Some_Stack_Type."="(A_Stack.Object, Another_Stack.Object) then ... 
    -- not nearly as nice as
  if A_Stack.Object = Another_Stack.Object then ...
 
Surely the increased readability is intuitively obvious! :)

Oh most certainly it is to me, getting rid of the silly Some_Stack_Type
prefix on "=" and deciding that you can use other means to figure out
where "=" comes from makes excellent sense to me.

The only trouble is, I would apply the same reasoning to the annoying
Some_Stack_Type. prefix on the Is_Empty call. Indeed I don't see the
difference between the two cases. Either it is a problem to have to
find out where things are, necessitating the verbose prefixs, or it is
not, and the situation seems the same in both cases to me :-) :-)

(the smileys are because this is an old discussion, hardlly worth repeating
unless someone has something new to say :-)
