[Boost-users] [preprocessor] concatenating values to create typedef permutations

Hi, I am trying to use the preprocessor iteration ability to create typedef permutations. I want to do something like use the following set of types TYPE1: char int float TYPE2: char int float double to generate permutations of MyClass such as typedef MyClass Mycc; typedef MyClass Myci; typedef MyClass Mycf; ... Any help would be greatly appreciated. Thanks, Chris
