### Boost.Proto Basic Includes and Aliases (C++)

Source: https://www.boost.org/doc/libs/latest/libs/proto/index

This snippet demonstrates the essential include directive and namespace aliases commonly used when working with Boost.Proto. It allows for unqualified use of Proto's wildcard pattern, simplifying expression template definitions.

```cpp
#include <boost/proto/proto.hpp>

namespace mpl = boost::mpl;
namespace fusion = boost::fusion;
namespace proto = boost::proto;

using proto::_; // Allow unqualified use of Proto's wildcard pattern
```
