I like it.
Not quite enough to do it now, though.
But I did commit my min3/max3 patch, because when I looked at it a bit
more, I realized that the old min3/max3 implementation was actually
completely and fundamentally broken, and has been for a decade since
it was rewritten in 2014.
I don't think anybody has actually hit the bug in practice (it will
cast away significant bits if you use it with just the right types),
but when I looked at it again I was like "Really? We've had that
horror for a decade?"
