When a regular expression is inputed, a set of pages which match will be outputed. That would be useful when using with subpage (although subpage is no longer used)
you can download title lists at http://download.wikimedia.org/ you can use Special:Allpages for page prefixes and you may provide an index methodology for regexp queries.

[[Special:Prefixindex]] does pretty much what you want, i guess
