Sometimes we want to let testers of a game insert their own comments during a transcript, without those comments wasting turns of the game or producing lengthy or inappropriate parser errors. Many testers have a habit of prefacing comments with a punctuation mark, so let's say that we'd like to catch any command that starts with any punctuation at all:
Test me with "x me / x troll / !this game is a bit dull so far / kiss troll / ? does this troll do anything? / :yawn".
Room description goes here...
You can see a scary troll here.
> x me
As good-looking as ever.
> x troll
You see nothing special about the scary troll.
> !this game is a bit dull so far
> kiss troll
The scary troll might not like that.
> ? does this troll do anything?
