boost mpl wrap each element in a set

I am trying to wrap each element in an mpl::set with some container, for example a std::vector, although the actual type is is not important. How would I do this? Basically I want to go from this

using mySet = mpl::set<int, float, double>;

to this

using myNewSet = mpl::set<container<int>, container<float>, container<double>>;

I thought of making a class similar to mpl::insert, however since I want the solution to be generic it has to somehow store the container type within itself, which doesn't play well with the parameter type of mpl::fold.

After some more searching, this seems to work fine:

using myNewSet = mpl::fold<
    mySet,
    mpl::set0<>,
    mpl::insert<mpl::_1, container<mpl::_2>
>::type;
