Eiffel Breaking Changes
Warning: Article under development
Introduction
The Eiffel language slowly evolved the past 20 years and added numerous new facilities. Initially, the changes were done by Eiffel Software while maintaining backward compatibility. Then, a major work was done between 2001 and 2005 to standardize the language which became an ECMA standard (ECMA-367) and an ISO standard (ISO/IEC 25436:2006). That work established some constructs initially implemented in EiffelStudio and also introduced some new ones. Most of the changes introduced by the standardization have been implemented but there are quite a few remaining. In some cases, it is due to the ration cost/benefit of the implementation, in some others it is a breaking changes.
This page is going to list all the changes that needs to be done by Eiffel Software to conform to the standard which cover both the language but also the library facilities required to support the language specification.
