Current macro is a POC that collects instances of a specific type (in current implementation Strings) into a list,
given an application built with traits containing those instances.

TODOs:
- Find a way to force a user to always use a macro method instead of building a list manually. Maybe through some implicit (given). As far as I can see that's not possible at the moment, because macro cannot mutate context AST, like adding some given instances to an application passed as a parameter to a macro. Maybe it will be possible in the future, say through an explicit tree typechecking. 🤷
- Examine self type annotation to determine which traits should be considered for search for a specific type instances also consider using an inheritance instead.
- Use some real-world examples
