But the version that was referenced here before isn't bulletproof,
right? Wouldn't the bullet-proofing reduce the readability?

I don't know enough about ctypes and its user community to answer that
(I doubt I'd have much direct need for it myself). But in general I'm
biased towards cross-platform tools.
