38. Summary, and What's Left To Come

• So, now you know all about literal characters, metacharacters and metasequences, how to get backreferences, how to search and how to search and replace.
• Now you can get out there, and start regex-ing!
• But, there's still a little more left to know:
  1. Greediness
  2. How regex engines work: DFA, Traditional NFA and POSIX NFA
  3. Why it matters how they work!
  4. Neat Perl-specific stuff: Regex modifiers: Case insensitive, global searches (including the use of the multi-match anchor) and Free-form regexes, lookahead and non-greedy quantifiers and Perl variable interpolation
  5. Regexes can't do everything!
• However, it'll have to wait for another time!
