approachingType
approachingType is a concept found in some programming languages and type systems that describes a method for determining the relationship between types. It's a way to establish if one type is a subtype of another, or if they are otherwise compatible. The core idea is to compare the structure and behavior of two types to ascertain their hierarchical relationship.
There are various approaches to defining and implementing approachingType. Some systems use structural typing, where compatibility
The purpose of approachingType is to enable powerful features like polymorphism and code reuse. By understanding
