A tutorial on using Java 21's pattern matching features, including sealed types and switch expressions, to simplify code and separate operations from types.
Explains the Visitor design pattern in Swift with code examples, showing how to add functionality to objects without modifying their original code.
Argues that Java's pattern switches are a simpler, more modern alternative to the traditional Visitor design pattern for separating operations from object structures.
Analyzes the relevance of the visitor design pattern in modern programming, comparing it to alternatives like dynamic_cast and discussing its core use case.
Explores C# dynamic dispatch behavior with class inheritance, highlighting a common pitfall when overriding methods in derived classes.
