I have noticed if bar is predefined or it is a number, it can be used as arguments. But can other strings be used this way?
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!".
