I might also add that str.startswith can accept a tuple of strings;
shouldn't that have been a set? :-)
I also had the thought that the backtick (`), which is not used in
Python 3, could be used to form character set literals (`aeiou` =>
set("aeiou")), although that might only be worth while if character
sets were introduced as an specialised form of set.
