Using mpl::remove, et al. I can eliminate types from an mpl::list. However, it appears that the result is not an actual mpl::list, but some sort of indexed, cons-like structure composed of mpl::l_item types. Is there a way to recreate an mpl::list proper using these l_item's?

E.g.

typedef mpl::list L; typedef mpl::remove::type R; typedef mpl::???<R>::type => mpl::list;

Not really. That type with the l_items acts just like list. In general with MPL you can't count on the exact types of sequences and integer constants. HTH Dave Abrahams BoostPro Computing
