It is legal; named access types implicitly convert to anonymous access types
as needed. (See 8.6(25)). That's even true in Ada 95, although the rule has
been broadened for Ada 2005.
To go to the named type from the anonymous one, you'd need a type
conversion.
But you may not need the named type at all, since anonymous types can be
used in almost all contexts.
