If bar is predefined, it *isn't* the string 'b':'a':'r':.
If bar is a number, it *isn't* a string.
So "other strings" is quite misleading.
In Haskell, if you use strings a lot, you are probably doing
something wrong. For things that are not text manipulation
tasks, there is practically always a better type, and these
days, for things that _are_ text manipulation, there is
practically always a better type.
A slogan I have programmed by since I first met C and recognised
how vastly superior to PL/I it was for text manipulation _because_
it didn't have a proper string type is "Strings are Wrong!".
