I am trying to create a list containing the permutations of a given type list.

The below code seems to function, though without the intended result, when I use a specified list instead of generating a new list by removing from the actual input. This is demonstrated by the difference between permutation_helper and broken_helper below.

Am I using remove incorrectly, or am I running into a different problem? <snip>

template< typename T> struct permutations;

template<typename value> struct permutations >: mpl::list1 > {};

A list containing 1 element is not guaranteed to be a specialization of list1. In Christ, Steven Watanabe
