Hi Matz !

I'm using Ruby 1.6.8.
Maybe my suggestions are already part of some later version,
or can be upgraded to some more fittable behaviour.

If no (or an empty) block is given, what would be the most common way to
'match' array elements ?
Regarding to Sean O'Dells 'weave example', I think it's like this:

natural = [1,2,3]
odd = [1,3,5]
even = [2,4,6]

matched = natural.match(odd,even)
matched #=> [[1, 1, 2], [2, 3, 4], [3, 5, 6]]
