Quote: an expression has a value; it may have two values, an L-value and an R-value [»straC8_1967] Quote: an expression specifies a computation that produces a value or variable; constant if determined at compile-time [»cardL_1991] Quote: a designator is an expression that denotes a variable or a variable's value; either readonly or writable
Quote: can delay evaluating an item until it is needed [»bentJL_1982] Quote: lazy evaluation separates the construction of possible answers from the selection of appropriate answers; e.g., Newton-Raphson [»hughJ_1984] Quote: lazy evaluation is a powerful tool for modularization Quote: modularity through higher-order functions and lazy evaluation; shows examples in lists, trees, numerics, and AI [»hughJ_1984] Quote: copy on write: don't allocate backing store for a copied page until write to it; lazy evaluation [»giffDK7_1985, OK] Quote: implemented temporary escrow of file encryption keys by lazy evaluation with a smartcard; may be equivalent to 3-DES [»blazM6_1994] Quote: bit-vector algorithm for lazy code motion subsumes loop invariant code motion, common subexpression elimination, and redundancy elimination; computation as early as necessary and as late as possible [»knooJ6_1992] Quote: wotdlazy, an efficient algorithm for write-only, top-down construction of suffix trees; less than 12 bytes per input character; faster and less space than McCreight's hash table implementation
