in thread Why aren't perl regular expressions really regular expressions?

recommended read Friedl's "Mastering Regular Expression" from O'Reilly.
Yes, I'm reading the first edition of Friedl's famous book (as well as about ten other Perl / related books all at once).

I specifially opened Mastering Regular Expressions looking for the answer to my above question, but couldn't find it.

    I just checked the history part in chapter 3 of the third edition.

    This information is at best hidden, there is a reference to a publication titled "The role of finite automata... ", that's all I could find.

    But I don't know any better source explaining the differences between dialects.
