Sorry... maybe the example was somewhat too simple. An example, which is
closer to what I need is the following (in "reality", f() is the
constructor of another class, but the one below does not work either):
class A
{
public:
A( const A& ){}
A( A& ){}
A( int ){}
A& ref(){return *this;}
};
int f( A& ){ return 3; }
int main (int, char **)
{
return f( A( 3 ) ); // error: could not convert `A(3)' to `A&'
return f( A( 3 ).ref() ); // works
}
i wonder why it is not possible to convert to A& outside of the temporary
object but inside.
regards,
Eric.
