- lazy evaluation — (reduction) An evaluation strategy combining normal order evaluation with updating. Under normal order evaluation (outermost or call-by-name evaluation) an expression is evaluated only when its value is needed in order for the program to return (the next part of) its result. Updating means that if an expression's value is needed more than once (i.e. it is shared), the result of the first evaluation is remembered and subsequent requests for it will return the remembered value immediately without further evaluation. This is often implemented by graph reduction. An unevaluated expression is represented as a closure - a data structure containing all the information required to evaluate the expression. Lazy evaluation is one evaluation strategy used to implement non-strict functions. Function arguments may be infinite data structures (especially lists) of values, the components of which are evaluated as needed. According to Phil Wadler the term was invented by Jim Morris. Opposite: eager evaluation. A partial kind of lazy evaluation implements lazy data structures or especially lazy lists where function arguments are passed evaluated but the arguments of data constructors are not evaluated.

- linear argument — (theory) A function argument which is used exactly once by the function. If the argument is used at most once then it is safe to inline the function and replace the single occurrence of the formal parameter with the actual argument expression. If the argument was used more than once this transformation would duplicate the argument expression, causing it to be evaluated more than once. If the argument is sure to be used at least once then it is safe to evaluate it in advance (see strictness analysis) whereas if the argument was not used then this would waste work and might prevent the program from terminating.
