Rationale for Ada 2005
Chapter 4: Structure and visibility
This chapter describes various improvements in
the areas of structure and visibility for Ada 2005.
The most important improvement is perhaps the
introduction of limited with clauses which permit types in two packages
to refer to each other. A related addition to context clauses is the
private with clause which just provides access from a private part.
There are also important improvements to limited
types which make them much more useful; these include initialization
with aggregates and composition using a new form of return statement.
