What are the advantages and disadvantages of Eiffel programming language?

Eiffel is known for its strong emphasis on software reliability and maintainability, featuring design by contract, which enhances program correctness through explicit contracts for classes and methods. Its object-oriented nature promotes code reuse and modularity. However, disadvantages include a smaller community and ecosystem compared to more popular languages, which can limit available libraries and resources. Additionally, the learning curve can be steep for those unfamiliar with its unique syntax and concepts.
