Ok, so it's not my fault :)

Or I could wrap it all in a boost::function like this so I can use the memfun
on an instance of TestClass:
TestClass t;
boost::function<void (TestClass*)> f(memfun);
f(&t);
But I'm not sure if that really adds something of value.. except the concept
to express that TestClass must be DefaultConstructible.
Anyway, thanks for your help!
