有啥霸气？
study本来就没人用啊

本来我看 perldelta  study 是加强了的，结果 5.16 出来之后它却成了 no-op，不知道最后的发布推迟有没有它的一份功劳

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!
