厂长:采用新的工艺流程可以大大减少炼铜车间所产生的二氧化碳。这一新流程的要点是用封闭式熔炉替代原来的开放式熔炉。但是，不仅购置和安装新的设备是笔大的开支，而且运作新流程的成本也高于目前的流程。因此，从总体上说，采用新的工艺流程将大大增加生产成本而使本厂无利可图。
总工程师:我有不同意见。事实上，最新的封闭式熔炉的熔炼能力是现有的开放式熔炉无法相比的。

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.
