Don't 'say' anything. Just let the optimizer spit out the QAST that you
are interested in looking at.
The following spits out a diff after optimization:
# diff -u <(perl6 --target=optimize -e '"test".IO.e') <(perl6
--target=optimize -e '"test".IO.e.Bool')

When I go to maintain this thing in five days or five
years and I have one of those "what the h*** is IO.d.Bool

I do this because it keeps me out of trouble.
I want back a yes or no answer, not True or Fail

That's a good point, but it's true that
Why do you have `.Bool` on all of the `.e` tests?
A file or directory either exists or it doesn't. So `.e` always returns a
Bool.
So there is zero reason to try to coerce it to a Bool.
You can look at the return value of `.e`.
