But how can you get the highest rainfall for 2006, or March, or Summer, via a
max(list,start) function?

With max(list[i..j],1), that's how.

So it should be either max(list) or max(list,start,end).

Obviously this is a "whee I can write some code" moment, and no real thought has
yet been put towards anybody actually finding the [] thing useful.
