perl - Perl split 如何准确地处理字符串？

Question

引自perldoc -f split:

As a special case, specifying a PATTERN of space (' ' ) will split on white space just as split with no arguments does. Thus, split(' ') can be used to emulate awk's default behavior, whereas split(/ /) will give you as many initial null fields (empty string) as there are leading spaces.

以上是关于split如何处理string分隔符的所有内容，但一般情况是什么，总是删除字符串分隔符的空前导字段？

Answer 1

不可以，只有当分隔符是一个字符串是一个空格时。在任何其他情况下，分隔符都被解释为正则表达式模式。
