Multiple Inheritance for other languages

Introduction

It would be great if in Eiffel we could multiply inherit from other classes written in a different language that does not support multiple inheritance. One easy way to do so is to create a tool that consumes an assembly and for each class of the assembly, it generates two new entities:

• an interface that collects all methods implemented in the existing class
• an implementation class that implements the above interface by using the bridge pattern (all calls are delegated to an existing object) and following what the Eiffel compiler expect to be generated so that it can do a correct dispatch.
