Prototypes are super buggy anyway, I should rewrite that as a pure function.

My code from 2016 for the hall of shame where I realized today that caseReplace could just return this.replace(o,m=>n.followCase(m)) instead.

socket.in wasn't behaving as advertised (broadcasting to all rooms). I decided to take matters into my own hands.

The for loop that counts to 10, but the last seven elements are completely useless.
