[Boost-users] tuple manipulators?

Would it be possible to have certain obvious tuple manipulators?

For example if A and B are 2 tuples have an easy way to
form the cross product of the 2 tuples?

That is if A is of length L, and B is of length M, to form
the tuple C of length L+M, containing copies of the elements
from both?

Also if D is a tuple of length N, and f is a functor taking
N arguments (of the right types) find some way to take 
f(D)  == f(D.get(1),D.get(2),...,D.get(N) )
Of course the ... is pseudo code. Fill in the appropriate list.

Of course I realize that limitations in the C++ language
may prevent doing this for arbitrarily large L, M, or N.
But it could be done for L, M, N, large enough so that
it is not a practical limitation?
