The documentation for regexp is missing some useful available features. Here are some that I noticed.

1) Lookaround operators such as (?=), (?!), (?<=), (?<!)

2) POSIX character classes [[:class:]] where class might be "alpha" or "alnum" or ...

3) non-greedy (?) and atomic (+) adjectives for repetition quantifiers [*+?].

4) Backreferences in patterns such as \1 or \k<name>

5) Comments within patternns using (?# comment ) syntax

6) Discussion of escape sequence processing such as '\n' => newline.

7) Expanded discussion of named tokens

8) Conditional patterns based on prior subpattern capture
