The only unary operator in Haskell is unary minus for negating numbers. There 
are no other predefined unary operators and it is not possible to define any. 
So unary minus is rather an exception in the Haskell language. But note that 
because of the way, function application is written, one can have notations 
similar to unary operators. For instance, there is
    not :: Bool -> Bool
and
    not <expression>
looks like applying an unary not operator.
