but what happens where there are two keys that share the same value?
You'll get the weather associated with one of the maximal values--which one is determined by the hashing algorithm and the text of the keys.
This is exactly the same effect as with your sort sort method.
and what is the 'l' option in the shebang ??
It sets $/ & $\ (INPUT and OUTPUT SEPARATORS) to \n. It just saves having to type . "\n"; each time. One downside is that if you use a module that uses "\n" explicitly when printing stuff, it ends up double spaced, but it's useful for standalone scripts.

In the absence of evidence, opinion is indistinguishable from prejudice.
