So it turns out that:
a) The book is incomplete. FatRat doesn’t have this behavior, but it’s not mentioned. I thought we were diving deep here.
b) The book is wrong. It is possible to create a Rat with a denominator larger than 64 bits, though it “usually” enforces that limit.
c) Perl6 is buggy. No surprise here.
