Naming and type safety.

Example: `File open(std::path, AccessMode)`
Usage: `auto file = open("myPath/filename.foo", AccessMode::Read | 
AccessMode::Write)`

- Named access to bits (Read/Write) instead of indices
- Type safety: AccessMode instead of std::bitset, and you can't pass 
e.g. Includes::All to AccessMode just the same as strong enums protect 
against a similar issue
