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

class}es.
