Because that's not why I wrote frak. Originally, I wrote it to help eliminate backtracking and, indirectly, minimize the state table of two enormous regular expressions within Vim's Clojure syntax file (the README has a link in the "Why?" section by the way).

Vim uses an NFA style engine and it was obvious to me that backtracking with these patterns would be an issue. Since we went to such great lengths to provide the most accurate regular expression highlighting possible for Clojure, which is pretty damn accurate, I figured we might as well try to make it performant. It turns out our efforts were not in vain.
