问题 Say for example I want to take this phrase: {{Hello|What's Up|Howdy} {world|planet} | {Goodbye|Later} {people|citizens|inhabitants}} and randomly make it into one of the following: Hello world Goodbye people What's Up word What's Up planet Later citizens etc. The basic idea is that enclosed within every pair of braces will be an unlimited number of choices separated by "|".
