Because if it's not static, then it needs a "this" pointer. The syntax for 
that is slightly different, but also possible:

                QFuture<void> f1 = run(this, SomeClass::hello,
                                        QString("Alice"));

Concurrent supports running function pointers, pointers-to-member-functions 
(provided the object is passed too, either as a const-ref or as a pointer) and 
functors.
