Oh oh oh my brain hurts!!! Neither "seq" nor "sep" are real words, both 
are abbreviations, they differ by a single letter, and the two letters 
are mirror images of each other!!!

This is a recipe for confusion when people get the order of sep and seq 
mixed up. Hopefully in real life code, you'd use a less easily confused 
function signature -- even just spelling out sequence and separator in 
full would reduce confusion to essentially zero.
