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>

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( );

yourBar.foo( );
return 0;

ctor( );
}
