Simen, could you please have a look at my dranges project?

Look at the algorithm and range sections, you'll find plenty of code that
try to tackle this.
In particular combinations() in algorithm2, and also tensorialProduct()
in
rangeofranges
combinations is a higher-order range that takes any number of forward
ranges
and output their combinations as tuples.
tensorialProduct does the same, but creates 'topology' : the combination
of
three ranges is a range, whereas the tensorial product of three (linear)
ranges is a range of ranges of ranges:
tensorialProduct([0,1],[2,3])
->
[[(0,2),(0,3)],
[(1,2),(1,3)]]
(where (x,y) indicates a tuple)
Indeed. I just had a quick look at the traits2 module last time you
linked it. This does seem to cover all bases. I have to say I'm impressed!
