Note Submitter: jo at durchholz dot org ---- Multiple inheritance, if designed properly into the language, most definitely is worth the trouble. Solutions exist for all associated problems (including the name clash issue mentioned above - identify a function by adding the name of the class where is was first defined, and all ambiguities vanish; make the class identification optional if nonambiguous, and it's even backwards-compatible). The rub is that it's difficult to get a language design that's simple to use, efficiently implementable, and applicable to a dynamically-typed language like PHP.
