tcfail168.hs:7:11: error:
    • Couldn't match expected type ‘IO a0’
                  with actual type ‘Char -> IO ()’
    • Probable cause: ‘putChar’ is applied to too few arguments
      In a stmt of a 'do' block: putChar
      In the expression:
        do { putChar;
             putChar 'a';
             putChar 'a';
             putChar 'a';
             .... }
      In an equation for ‘foo’:
          foo
            = do { putChar;
                   putChar 'a';
                   putChar 'a';
                   .... }
