I've been using true_type and false_type in some of my interfaces, for example:
https://github.com/erikerlandson/edit_distance/blob/master/include/boost/algorithm/sequence_alignment/edit_distance.hpp#L62

However it seems as though true_ and false_ are more compatible with MPL logic functions.  Is there any particular reason to use one over the other?   Would it be preferable to use true_ and false_?
