The MPL lambda template type parameter of the functor that is passed to Fusion causes the trouble. This functor is used by Fusion as a template type parameter for an internal metafunction class which turns into an (invalid) lambda expression due to the nested placeholder. Making 'preds' a metafunction class, e.g. via mpl::quote1, should make your code compile fine.
I figured that. Using mpl::lambda also fixes the problem. Glad it is only that ^^ Thanks for the insight :)
