Given and example like this:
class A {}
class B is A {}
class D is B {}
say D.^parents(); # ((B) (A))
say D.^parents( :all ); # ((B) (A) (Any) (Mu))
So, I conclude that Any and Mu are "hidden" as far as ^parents is concerned.
According to the documentation, ^mro_unhidden does this:
"Returns a list of types in method resolution order, excluding
those that are marked with is hidden."
And yet, what I see is:
say D.^mro_unhidden; # ((D) (B) (A) (Any) (Mu))
So why does this include Any/Mu?
A somewhat related question: How do you check whether a trait is set
on something?
Can you get a list of all traits?
