When block based languages evolved into modular languages (Ada, Modula-2) they added a system with two levels: public and private declarations. C got the same job done with its header files and separate compilation and eventually was able to enforce that with "static" function declarations. If you have these two levels you will rarely (if ever) need extra ones. -- Jecel
