试谈Tcl的闭包

为在Tcl编程语言中加入闭包（匿名函数）,先对Tcl和闭包进行必要的了解,结合两者的特点,提出了针对Tcl的闭包解决方案,通过在闭包代码段前增加上下文环境信息以及组成,以列表参数和代码段为基础的闭包结构,成功地模拟出了闭包这一编程特性,给简化Tcl代码和优化Tcl代码结构提供了一个简单而高效的工具。

Brief Introduction of Closure in Tcl

To embed characteristic of closure to Tcl,we take a look at Tcl and closure briefly and put forward a solution by adding context information in the front of closure code and forming the structure of closure composed of arguments list and code block.It is a simply but effective tool to simplify the way of Tcl programming and code optimization.
