+- Handle colon-separated locations (e.g., `London:Paris:Berlin`)
+- Process and display weather for multiple cities in one request

+This is advertised as a feature in wttr.in, but it does not work on the live
+site. Given that this would be an unbounded computational risk and a DOS vector,
+this is not going to be implemented. That can be done easily through a script,
+and it will allow the rate limiting to work better that way
