To aid in the usage of classes that have the sole intent of being called. Surely though the compiler team will say this is not *needed* and can be achieved using normal method calls.

Question to Blaise, how is this adjacent to closures? I just see it as an operator overload, i.e. how C++ allows to overload the () operator.

I will also say In my attempt to make a "default property" which could be used for smart pointers Sven specially said absolutely no to the idea of overloading the "." operator so I tend to think this idea won't go far.
