7. Declaration and assertions
Note that the declared length is 0;
Perl has a set of statements that control case sensitivity and code change:
\ U converts the next letter to uppercase;
\ L to lower the next letter;
\ U converts the remaining characters of the text to uppercase;
\ L converts the remaining characters of the text to lowercase letters;
\ Q performs code replacement for characters other than letters until \ e Dec
assertion is only valid in the use of ' eval ' compiled instruction Fu Shicai;
(? >pattern) If the type is locked in the current position, use a separate pattern to match the substring. If the regular expression/^ (? >a*) ab/never match, because the statement (? >a*) matches all the a characters at the beginning of the string and deletes the character a that matches AB;
(!(!=pattern) A declaration, which is contrary to the previous view statement meaning;
(? (condition) yes-pattern|no-pattern)
