-- infix, prefix, postfix 
-- in Java:
      function calls are prefix  min (3, 2)
      unary operators are prefix or postfix, depending on the operator
            ++ i
            i --
            ~ 0xFA   gives result 0x0D
            
{-  infix/postfix
 3 + ( 2 * 7)  === 3 2 7 *
 (4 + 5) * (15 + 16)  === 4 5 + 15 16 + *
 more example on the fly
 
 infix/prefix
 3 + ( 2 * 7)  === + 3 * 2 7
 (4 + 5) * (15 + 16) === * + 4 5 + 15 16
 
 NB  parentheses to force precedence is not necessary for prefix, postfix,
     but are necessary to force (change the default) precedence for infix

-- Haskell is prefix. Only

-- can use function name as infix operation using backticks:
-- min 10 20
-- 10 `min` 20

-- creating Haskell file (baby.hs), create simple function (doubleMe on p 5)
-- load Haskell file ( :l baby)
-- run functions in the file
