这是因为尽管从不同的散列中获得同一个字符串的返回值，但是将关键字链接到散列上也只是时间的问题。

This is because although completely different hashes are returned for the same string, it just becomes a matter of time before keys are linked to hashes.

perfectproperty：查找时间复杂度为o(1)的表条目—就是说，至多需要一个字符串比较执行静态搜索集中的关键字识别。

Perfect property: Locating a table entry requires o (1) time-that is, at most, one string comparison is required to perform keyword recognition within the static search set.

不是每一个字符串都是合法的rexx符号——为限制程序库中的关键字——但是相对于大部分语言，Rexx在符号命名方面非常自由。

Not every string is valid Rexx symbol — which restricts the keys in the dictionary — but Rexx is pretty liberal about its symbol names, compared to most languages. E.g.
