This has a side effect of not allowing mpl::list to be used as the sequence, even though it is an MPL front extensible sequence (stated as required for the signature argument of, say, make_function). The solution is to use mpl::deref::type instead of Sig_iterator::type." Bugs new Boost 1.39.0 python USE GITHUB Boost 1.38.0 Problem
