Module:Separated entries

-- This module takes positional parameters as input and concatenates them with

-- an optional separator. The final separator (the "conjunction") can be

-- specified independently, enabling natural-language lists like

-- "foo, bar, baz and qux". The starting parameter can also be specified.
