For the present you can/should use R::A or one of the other regex modules as they should be patched in time of 5.10 to utilize the TRIE optimisation if possible. OTOH You havent really spelled out if you mean an anchored match or not. Ie is it /^(list|of|strings)$/ or is it /^(list|of|strings)/ or is it /(list|of|strings)/? Depending on which there may be non regex based strategies that are quite competitive.
