That statement was true in the Perl4 days (back over a decade ago). Perl5
added a huge pile of new features to regexen, and continues to make
incremental changes on each new release (the upcoming 5.10 will have named
captures, for example).
Emacs regexps are comparable to regexps available in other
widely-available languages and tools.
This is a bit of a weaselword, since *everything* is "comparable". :)
