 {{{otherwise}}} is frequently used and therefore should have been written
 as a keyword.\\

 {{{otherwise}}} was coded in prelude like this {{{otherwise = True}}}\\
 So what is the reason that {{{otherwise}}} was not coded as a keyword?\\
 \\
 To understand you have to go back. It seems that this has been done to
 minimize the number of keywords.\\

 Today it seems surprising. And I wonder why we wrote the conditional
 expression with {{{if}}}{{{then}}}{{{else}}}?
 That's three additional keywords.\\
 \\
 It would have been better to write the conditional expression as in Sasl
 {{{condition -> exp1 ; exp22}}} (By adapting the operators of course.)\\
 Let's go back to {{{otherwise}}} . And take a look at this code.\\

 {{{
 otherwise :: Bool
 otherwise = Prelude.otherwise

 sig :: Integer -> Integer
 sig n  | a   = -1
          | b   = 0
          | Main.otherwise = 1
    where { a = n < 0;
                 b = n == 0 }

 z :: Bool
 z = if Main.otherwise == Prelude.otherwise then True else False

 main :: IO ()
 main = do {
                  print (sig 0);
                  print (z) }

 }}}
 This code works but the compiler result is different by adding or removing
 the first two lines of code.\\
 For me it is urgent that {{{otherwise}}} become a keyword as in Miranda.
