Eiffel

Eiffel is a high-level, object-oriented programming language designed by Bertrand Meyer and Eiffel Software. It is used for developing software components in a wide range of industries, including aerospace, automotive, finance, healthcare, and telecommunications. Eiffel is based on the concept of design by contract, which allows developers to create software that is more reliable and easier to maintain. Eiffel is also statically typed and supports multiple inheritance, so it is easy to create robust and reusable software components. Eiffel is available under the GPL and commercial licenses. Eiffel Software also offers a number of tools and libraries for developing Eiffel applications. If you are looking for a powerful and flexible programming language for developing software components, then Eiffel is definitely worth considering.
