Go up one level in this thread

 I didn't do any implementation.
 The idea was to use it as a relatively cheap test to exclude the possibility of
a repetition. A small bit array is a pretty small and affordable plot of memory
real estate. And since there are no false negatives it would be perfectly safe
to use.
 The only question is if it would have been made fast enough and selective
enough to amortize over a traditional repetition check. This will of course only
be the case if it is faster than the implemented repetition check.
