  overloading
       
           (Or "Operator overloading").  Use of a single
          symbol to represent operators with different argument types,
          e.g. "-", used either, as a monadic operator to negate an
          expression, or as a dyadic operator to return the difference
          between two expressions.  Another example is "+" used to add
          either integers or floating-point numbers.  Overloading is
          also known as ad-hoc polymorphism.
       
          User-defined operator overloading is provided by several
          modern programming languages, e.g. C++'s class system and
          the functional programming language Haskell's type
          classes.
