specialisation

A reduction in generality, usually for the sake of increased

efficiency. If a piece of code is specialised for certain

values of certain variables (usually function arguments), this

is known as "{partial evaluation}". In a language with

{overloading} (e.g. {Haskell}), an overloaded function might be

specialised to a non-overloaded instance at compile-time if

the types of its arguments are known.
