Support for enforce library

Any plans to allow [runtime type enforcing](https://github.com/RussBaz/enforce)?
I attempted to use the enforce decorator `@runtime_validation` but for the `data` types (coconut named tuples, while enforce expects [`typing.NamedTuple`](https://github.com/RussBaz/enforce#namedtuple)) I couldn't get it working.

```
Argument 'pinfo' was not of type . Actual type was untyped PathInfo
```

Do you have any opinion on supporting that or idea how to cope with it?

No files, tests, or entry points are named. Start by examining Coconut's generated data types and named-tuple handling alongside enforce's runtime_validation and typing.NamedTuple requirements. Done would mean a decided approach and documented or implemented support for validating Coconut named tuples.
