If you insist on a one-liner for four separate operations, what's wrong with
this?

", ".join([block(x) for x in sorted(foo.array_of_things)])

Or if you prefer map:

", ".join(map(block, sorted(foo.array_of_things))


I think I would be less skeptical about fluent interfaces if they were
written more like Unix shell script pipelines instead of using attribute
access notation:

foo.array_of_things | sort | map block | join ", "
