The text explores the complexities and expressiveness of programming languages, highlighting how advancements such as lambdas in Java and C++'s `constexpr` have improved code readability and reduced boilerplate. It discusses how these features, while beneficial to experienced developers, can introduce a steep learning curve for newcomers, leading to potential confusion when encountering complex or overly concise code. The article uses examples from various programming languages, including Java, Scala, C++, and Rust, to illustrate how expressive features can both enhance and obscure code clarity. It argues that while expressiveness is generally a win for experienced users, it can lead to jargon-like code that is difficult for outsiders to understand, urging programmers to balance the use of advanced features with accessibility for others who may inherit the code. The author suggests that while showboating is rare, programmers should strive for clarity and avoid overly complex solutions in shared codebases.
