They're the most obvious example, from my point of view.

I tend to write stuff like

	foo.array_of_things.sort.map { block }.join(", ")

I like this a lot more than
	array = foo.array_of_things
	sorted_array = array.sort()
	mapped_array = [block(x) for x in sorted_array]
	", ".join(mapped_array)

(I am still not used to Python's attachment of join to strings rather
than to arrays.  I don't really object to it, it's just not how I think
about join operations.)
