Type embedding: Golang's fake inheritance

Golang allows for type embedding, which is a way to embed a type inside another type using a struct. It gives a syntactic shortcut for accessing all of the embedded type's fields and allows you to share methods on the embedded type.

However, it's important to note that type embedding isn't inheritance, and pretending it is will lead to bugs. Common use cases where the analogy between type embedding and inheritance breaks down include special keywords, such as "this" in Java, method chaining, and interface embedding.

Despite its flaws, type embedding is still widely used, but it's crucial to be aware of Golang's limitations and write code defensively with them in mind.
