I thought that in:

          static assert (__traits(isPOD, T) );
          return    cast(T*) bfHdr.user_.ptr;
    }
the line:
static assert (__traits(isPOD, T) );
would test for there not being any embedded refs, pointers, 
etc., but
unittest
{
...
    struct    thead2    {    string    test;    }
    auto    userTest2    =    bf.user!(thead2)();
}
executes without complaint.  Is there a better way?

There's std.traits.hasIndirections
