But when you have a very common idiom and a fact that many people waste lots of time figuring out they had a LIST containing a single vector and debug, maybe it would have made sense to have either a sister function like strsplit_v() that returns what is actually wanted or allow strsplit(whatever, output="vector") or something giving the same result.
