Closest Wikipedia entry:  Evaluation strategy — In a programming language, an evaluation strategy is a set of rules for evaluating expressions. The term is often used to refer to the more specific notion of a parameter-passing strategy that defines whether to evaluate the parameters of a function call, and if so in what order (the evaluation order) and the kind of value that is passed to the function for each parameter (the binding strategy). The notion of reduction strategy is distinct, although some authors conflate the two terms and the definition of each term is not widely agreed upon.To illustrate, a function application may evaluate the argument before evaluating the function's body and pass the address, giving the function the ability to look up the argument's current value and modify it via assignment.Evaluation strategy is specified by the programming language definition, and is not a function of any specific implementation.
