1). That's only accurate to 10**83. Which is to say, it's as accurate as
a double gets -- 16-17 digits. (BTW, that is a legal Rat.)
I admit don't really know what to do with this.

should have is a quick and easy
way to convert from Num to FatRat with minimal loss of precision. I
believe right now the default Num -> FatRat conversion also uses 1e-6 as an
epsilon, which seems wrong to me.

My understanding is it is intended that parsing can work on Cats

s implementation is that it always
tests against the first 256 primes, so it also takes advantage of this
in correctness, if possibly not in speed.

Well, hyperoperators work fine on Hashes, they operate on the values,

Certainly doesn't work in Rakudo and I've never seen a spectest

thanks all of our contributors and sponsors for
making Rakudo Perl possible, as well as those people who worked on parrot, the
Perl 6 test suite and the specification.
The following people contributed to this release:

That is, adding a .Seq between the two sorts clears up the problem.
That is admittedly a hack, but it is a simple one.
Thanks for reporting the problem!

And just to finish it off... are you allowed to do 'class B { ... }'
even after "declaring the real B"?

fail just returns an uncalled exception. What does that do in a where block?

What's your objection to FatRat.new(45207196, 11 ** 37)?
