Yes! I mean, I have no idea, but it seems like it's worth a look at
anything that promises to replace some of the unsafePerformIO hacking
with more functionally transparent ways to do the same thing.
I love talking about the questionable purity of sin! but as it happens,
since I don't do that much geometry I am without sin anyway.
