8// This file provides forward declarations of the most important I/O
9// classes.  Note that almost all of those classes are class templates,
10// with default template arguments.  According to the C++ standard,
11// if a class template is declared more than once in the same scope
12// then only one of those declarations may have default arguments.
13
14// <iosfwd> contains the same declarations as other headers, and including
15// both <iosfwd> and (say) <iostream> is permitted.  This means that only
16// one header may contain those default template arguments.
17
18// In this implementation, the declarations in <iosfwd> contain default
19// template arguments.  All of the other I/O headers include <iosfwd>.
