有啥霸氣?
study本來就沒人用啊
本來我看 perldelta study 是加強了的,結(jié)果 5.16 出來之后它卻成了 no-op,不知道最后的發(fā)布推遲有沒有它的一份功勞
5.15.0
The study function could become confused if fed a string longer than 2**31 characters. Now it simply skips such strings.
5.15.1
You can now study more than one string
The restriction that you can only have one study active at a time has been removed. You can now usefully study as many strings as you want (until you exhaust memory).
If a studied scalar is split with a regex, the engine will now take advantage of the study data.
5.16.0-RC0
study is now a no-op.
5.16.0-RC1
study is now a no-op, presumably fixing all outstanding bugs related to study causing regex matches to behave incorrectly! |
