对象就是数据和函数的集合。
那就是说,如果函数有确定的有效值集合或范围可作为参数,可以将检验参数是否有效的断言放在该函数代码的第一行。

然后我将一个新的集合附加至由factor列表中的map函数生成的factor上,应用此代码生成对称的(平方根上方匹配的因子)列表。
I then append a new collection onto factors - generated by the map function on the factors list - applying the code to generate the symmetrical (the matching factor above the square root) list.
清单14中的tree - zipper实现的函数支持核心集合类型,允许将通过这些类型构建的任何Clojure数据结构作为zippers: branch ?
The tree-zipper in Listing 14 implements the functions that enable the core collection types to allow any Clojure data structure built from those types to become a zipper: branch?

We have two files, utils_left.php and utils_right.php, which are collections of utility functions for right - and left-handed users.
值得注意的是,您在执行其他查询函数时不能在指针和结果集上执行distinct函数,而应直接在集合上执行。
It's worth noting that you do not perform the distinct function on a cursor or result set as you do other query functions, but you perform it directly on the collection.
