Seeing your code in svn, wouldn't also a flatten() (or, concat() ) function
be interesting? It transforms a range of ranges (of whatever depth) into a
linear range.

Also, interpose(range, element) that returns range[0], element, range[1],
element, etc.
and interleave(range1, range2) that produces range1[0], range2[0],
range1[1], range2[1], range1[2], ...

Isn't joiner just chain(interpose(["Mary", "has", "a", "little", "lamb"],
"...")?

std.range.transversal is a bit... short on this one: it just iterates
through a 'vertical' slice.
