With boost 1.47 (spirit 2.5) utree if officially part of a boost release.

Artem and I have discussed refactoring mapnik::value to move from variant to utree for performance gains: smaller,faster value access. Might have implications for what is possible with expressions - also Carto C++ is already leveraging utree.
