Hi,
    When compiling the following program, I got error :

lespoir:/local/home/wongm 107 > g++ -o doo doo.cc
doo.cc: In function `int ctor()':
doo.cc:27: request for member `foo' in `myBar(Foo)', which is of non-aggregate type `Bar ()(Foo)'
doo.cc:29: no matching function for call to `Bar::Bar (Bar ()(Foo))'
doo.cc:15: candidates are: Bar::Bar(const Foo &)
doo.cc:16:                 Bar::Bar(Bar &)
doo.cc:29: in base initialization for class `Bar'

It seems that gcc does not think of myBar is an object, 8-((

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#include <stream.h>

class Foo
{
public:
   Foo(int) { };
   ~Foo() {} ;

   void bar( ) { cout << "bar called" << endl; } ;
};

class Bar
{
public:
    Bar(const Foo&) {};
    Bar(Bar&) {};
    ~Bar() {};

    void foo( ) { cout << "foo called" << endl; };
};

const int myInt = 7;

int ctor()
{
    Bar myBar(Foo(myInt));
    // myBar.foo( );
    // Bar yourBar(  Bar &myBar = Bar( Foo( myInt ) ) ); /* works */
    Bar yourBar( myBar );

    // Bar yourBar(Bar(Foo(myInt))); /* works */
    yourBar.foo( );


    return 0;
}

main( )
{
    ctor( );
}
