I'd be surprised to see lists longer than low tens of elements. For similar functionality the dash library provides `-distinct', which uses a lookup table if there are more than 32 elements in the list, claiming that this is the break-point for the hash based approach to be faster. I'm a bit loath to just re-implement that. Am I allowed to depend on dash? (I'd guess not, but figured that it's worth asking.) dme. -- Why stay in college?
