Oh. How do I make my code work with old versions of MPL and new? There 
is no mpl/version.hpp or a macro I can test for conditional compilation 
AFAICT. I'll have to avoid both mpl::apply_if and mpl::eval_if and roll 
my own. :-(

Is there a doc to help people migrating from the old to the new MPL? A 
list of differences?
