Ada always had anonymous array types:

V : array (1 .. 10) of Duration;

Anonymous access types in the form of access parameters were introduced in Ada 
95, to make passing a pointer to an imported function from C (or similar 
languages) easier. Never mind that a named convention-C access type did the job 
just fine. More recently, we've been treated to a whole slew of kinds of 
anonymous access types, apparently to make C-in-Ada easier to write.
