I tend to write stuff like

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)
If you like the one-liner, this is readily written as
", ".join(block(x) for x in sorted(foo.array_of_things))
Modulo your gripes about string.join(), this is about as succinct
(and more readable, IMHO) as your initial example. I've got
piles of these sorts of things in my ETL code.
