FWIW, I don't think "compact" is generally a good goal for code.  Being
readable is 100x more important than being compact and being un-compact
is only a problem when it hurts readability.

For a function like the one in question, having the individual return
conditions clearly commented is way more important than saving 10 lines
of code.
