Special words such as static in bold italics stand for themselves, unquoted. To the Eiffel developer, add looks like a normal object-oriented feature, which takes only the expected argument.
Further examples appear below.
There is no need for an extra argument in the case of static member functions, constructors and data members. It will translate these declarations into Eiffel wrapper classes. If there is no constructor, it will produce a creation procedure with no arguments and an empty body. You should always inspect the result and be prepared to adapt it manually. The final details are left to the Eiffel software developer.
