In ''Apocalypse 5'', Larry Wall enumerated 20 problems with "current regex culture". Among these were that Perl's regexes were "too compact and 'cute'", had "too much reliance on too few metacharacters", "little support for named captures", "little support for grammars", and "poor integration with [the] 'real' language".<ref>{{cite web | url=http://dev.perl.org/perl6/doc/design/apo/A05.html | title=Apocalypse 5: Pattern Matching | author=Wall, Larry | date=[[2002-06-04]] }}</ref>
