A typical __(66)__ language contains an applicative sub-language which approximates the mathematical abstractions of "timeless" functions applied to 'spaceless'values, where the actual operation sequences and use of storage space during expression evaluation are organized behind the __(67)__ .In this setting, values are data structures of low volume, typically a few computer words or less, which means that an illusion of spacelessness can be realized by having __(68)__ results during expression evalution stored at the discretion of the language implementation, and effecting parameter __(69)__ and __(70)__ operations through value copying.
