Eiffel is arguably the best commercial object-oriented language
available today (Jim Rumbaugh).
We settled on Eiffel because it provides the right paradigms to
address the construction of large, high-quality object oriented
software systems and is quite easy to master (authors of Design
Patterns and Contracts).
Eiffel is more than a language; it is a framework for thinking
about, designing and implementing object-oriented software (Richard
Wiener).
