 choose to not implement the classic automata approach of transforming
 regular expressions into NFAs and then DFAs---because we simply do not
 know how such back-references can be represented by DFAs.

+We also plan to implement the bitcoded algorithm
+in some imperative language like C to see if the inefficiency of the 
+Scala implementation
+is language specific. To make this research more comprehensive we also plan
+to contrast our (faster) version of bitcoded algorithm with the
+Symbolic Regex Matcher, the RE2, the Rust Regex Engine, and the static
+analysis approach by implementing them in the same language and then compare
+their performance.
