This is a known shortcoming of Boost.Accumulators. Things get
complicated when t*t has a different type than t and such. Sprinkling
BOOST_DECLTYPE (or decltype where it's supported) would solve the issue,
but finding all such assumptions everywhere would be hard. Appropriate
use of a degenerate numeric archetype in all the tests would do it, but
adding that and then adding decltype everywhere would be a big job. But
you should file a bug, anyway.
