Part of the problem is a lack of agreement on what 'regular expression' means.
Twenty years ago, there was. Calling a extended re-derived grammar expression like Perl's a 'regular-expression' is a bit like calling a Hummer a 'car' -- perhaps to hide its gas-guzzling behavior.
Strictly speaking, PCREs aren't regular expressions at all, for some values of the term 'regular expression'. See http://en.wikipedia.org/wiki/Regular_expression
