Fusion includes a number of binary functions such as join, equal, less, etc.

Looking at the code suggests that they just work element by element in 
sequential order.

But what about associative tuples?  For example

struct account {};
struce amount {};

typedef  boost::fusion::set<
    account,
    amount
> debit;

typedef boost::fusion::set<
    amount,
    account
> debit2.

clearly the types are meant to be the "same" so I would expect

boost::fusion::join(debit, debit2) to function and return one type.
I'm thinking it doesn't do that.  Any observations/suggestions that any 
Fusion
guru would like to share would be appreciated.
