Lazily joins a range of ranges with a separator. The separator itself
is a range.
Example:
----
assert(equal(joiner([""], "xyz"), ""));
assert(equal(joiner(["", ""], "xyz"), "xyz"));
assert(equal(joiner(["", "abc"], "xyz"), "xyzabc"));
assert(equal(joiner(["abc", ""], "xyz"), "abcxyz"));
assert(equal(joiner(["abc", "def"], "xyz"), "abcxyzdef"));
assert(equal(joiner(["Mary", "has", "a", "little", "lamb"], "..."),
"Mary...has...a...little...lamb"));
