Comment (by anonymous):

 Hm. That could be problematic.

 Since initializer lists only take on template argument, we should be able
 to do the following:

 replace

 template< class Container >
 operator Container() const

 with

 template< template<class,class> Container, class T, class A >
 operator Container<T,A>() const

 Furthermore, this only takes care of templates with two arguments like
 standard sequence.
 Therefore, we also need to add overloads with 3 and four arguments.

 A bigger problem arises with something like boost::multi_index_container
 which may have many template arguments ... hm ... maybe the C++11 solution
 is to use variadic templates to cover all cases with more than one
 template argument.

 If you can make a patch and test it, I'd be happy to apply it.

 regards
