The areas mentioned in this chapter are not specifically mentioned in the WG9 guidance document [1] other than under the request to remedy shortcomings and improve the functionality of access types and dynamic storage management.

The following Ada Issues cover the relevant changes and are described in detail in this chapter:

These changes can be grouped as follows.

First there are some minor changes to elementary matters such as the placement of pragmas, labels and null statements (100, 163, 179).

An important addition is the introduction of more user-friendly mechanisms for iterating over structures such as arrays and containers (139, 212, 255, 292).

Further flexibility for storage management is provided by the introduction of subpools of storage pools (111, 190, 252). A number of issues concerning anonymous access types and allocators are also resolved (148, 149, 193, 253).

A number of new Restrictions identifiers have been added. They include No_Standard_Allocators_After_Elaboration, No_Anonymous_Allocators, No_Implementation_Units, and No_Implementation_Identifiers. A blanket new profile covering a number of restrictions, No_Implementation_Extensions, is also added (152, 189, 241, 242, 246, 272).

Finally, there are a number of minor unrelated improvements. Four are actually classed as binding interpretations and so apply to Ada 2005 as well; they concern nominal subtypes (6), address of intrinsic subprograms (95), time in the package Calendar (119), and class wide operations on formal generic subprograms (71). The other miscellaneous issues concern the composability of equality (123), and tags of abstract types (173).
