You're very wrong, backreferences in general can't be translated to finite automata (NFA is short for nondeterministic finite automaton). See these comments:

You say:

> resistant to catastrophic backtracking despite features which normally translate to nfa

I interpret this as you equating NFA with backtracking engines, which would be incorrect. Is my interpretation wrong?
