What kind of bench test are you using Derek? I get nowhere near those 
kinds of results.

what is your average iteration time?

I use..
  match_pattern({1,2,3,1,4,3,3,2,5,3}) -- ZIGZAGGING
..in an iterated loop

I don't think I can even iterate 50x in 1.48 seconds
And that pattern is on the faster side of the avergage.

I don't understand how you could possibly get it that fast, unless your 
pattern is {1}, only then is my program comparable to your results.

I've still got some tweaking to do, but I don't see it getting much 
faster.

Try...
-- find all 7 letter words with unique letters
match_pattern({1,2,3,4,5,6,7})

I'd like to know what your iteration time is for that one.
