It is. It did not use the concept at that point. After inspecting I 
remembered why, and it is fixed now (in Boost.Trunk).

Thanks for the minimal file, it is helpful. So fixed in Trunk, sorry for 
the error. If you don't use Trunk, I can send you the modified  file as 
an attachment, which you can replace.

Thanks for the catch.
