Counter argument here would be that sometimes knowing the structure type is practical, like if you are using inflection.

But inflection is bad, and again it’s a specific usecase. So making it a global rule’ is kinda overkill.

Interesting. I've seen the interface match the class when its a service. ex. IDataService and DataService. The 'I' is used to distinguish between the 2 files easily. The interface is needed for dependency injection.

I have seen that argument somewhere before, but i still wonder.
Would the class definition not suffice as the type?

I mean dependency injection systems usually just manage shared instances.

Maybe it's language dependent and i am just missing a piece of the puzzle. :/
