Hi Tiankun,

the advantage lies in the fact that the user of your block just has to
look at the block_name.h (and also SWIG), and you can exchange,
implement, extend and subclass your implementation to your heart's
delight in the block_name_impl.h. This simplifies SWIG wrapping a lot,
and thus has, at least for me, decreased development complexity
significantly.

Greetings,
Marcus
