Multiple inheritence

This was the question asked to me during an interview. What all languages support multiple inheritence?
The answer is:


The definition of the Title is simple and self explanatory. BTW all this info is from: http://en.wikipedia.org/wiki/Multiple_inheritance.


Languages that support multiple inheritance include: Eiffel, C++, Dylan, Python, Perl, Perl 6, Curl, Common Lisp (via CLOS), OCaml, Tcl (via Incremental Tcl)^[1], and Object REXX (via the use of mixin classes).

Diamond problem:

 Multiple inheritance allows a class to take on functionality from multiple other classes, such as allowing a class named StudentMusician to inherit from a class named Person, a class named Musician, and a class named Worker. This can be abbreviated StudentMusician : Person, Musician, Worker.

Ambiguities arise in multiple inheritance, as in the example above, if for instance the class Musician inherited from Person and Worker and the class Worker inherited from Person

C++ requires that the programmer state which parent class the feature to use should come from i.e. "Worker::Person.Age". C++ does not support explicit repeated inheritance since there would be no way to qualify which superclass to use (see criticisms). C++ also allows a single instance of the multiple class to be created via the virtual inheritance mechanism (i.e. "Worker::Person" and "Musician::Person" will reference the same object).
