As mentioned, this is a matter of style. However, in a lot of cases, in
order to get the return at the very end, it's necessary to put endless
if/else pairs in the function. That makes it hard to read the source.
I'm sure there are purists out there who would insist the single return
go at the end. But expediency and readability may dictate otherwise.
