Wrappers and iterators examples
===============================

Build and run:

```
make
```

`raw_ptr.cc`
------------

Simply raw pointer wrapper. Shows how we can do an object abilities extension in the runtime. Useful for iterators.

`smart_ptr.cc`
--------------

Similar example, but holds the shared pointer.

`iterable.cc`
-------------

Finally, the iterable with traversing algorithm compile-time instantiated. The template method returns an iterable object, which iterates over IShape's with its `.get_next()`/`.get_prev()`.
