Comment (by Kohei Takahashi <flast@…>):

 It is not a bug, but by design.
 [http://www.boost.org/doc/libs/1_60_0/libs/fusion/doc/html/fusion/sequence/intrinsic/functions/at_c.html

 fusion::at_c] requires `Random Access Sequence`, but
 [http://www.boost.org/doc/libs/1_60_0/libs/fusion/doc/html/fusion/algorithm/transformation/functions/join.html

 fusion::join] returns
 [http://www.boost.org/doc/libs/1_60_0/libs/fusion/doc/html/fusion/view/joint_view.html

 fusion::joint_view] i.e. `Forward Access Sequence`.
