is it possible to call nonconst member function on an unnamed temprary?
ex:
class String{
public:
void doSomething();
};
String createString();
createString().doSomething();
is it ok?
thanks.

It's OK
Because the unnamed temprary returned by "createString" is destroyed at
the end of the full expression. It's no mean that the unamed temporary
object is constant. So the temporary on the full expression does't go
out of scope and you can do anything with it.
