Comment(by djowel):

 The docs read as: "Currently tuple is basically a synonym for vector,
 although this may be changed in future releases of fusion. "

 That should be understood as "Currently fusion::tuple is basically a
 synonym for fusion::vector, although this may be changed in future
 releases of fusion. "

 I believe this claim holds. You can use fusion::tuple and fusion::vector
 interchangeably. The claim does not imply that boost::tuple is a synonym
 for fusion::vector as your patch requires. I tried your code and the
 compiler barfs when it gets to the point where it expects *invalid*
 expressions like Tuple::head_type. If the code adheres to only the API of
 TR1::tuple and/or fusion::vector, then all is well.
