Re: What does ^methods really tell you?
Thanks much-- so there's an explicit cut-off at the (Cool)/(Any) level...
It seems peculiar that there's often a lot of duplicates in the list,
including mysterious entries like "Method+{is-nodal}.new".

"Returns a list of public methods available on the class (which includes methods from superclasses and roles). By default this stops at the classes Cool, Any or Mu; to really get all methods, use the :all adverb. If :local is set, only methods declared directly in the class are returned." https://docs.perl6.org/routine/methods On 2018-07-31 06:56:07 +0430, Joseph Brenner wrote: > I originally thought that $var.^methods gave you a list of all > available methods on $var, but it looks like it doesn't (always?) > report on inherited methods. > > my $stringy = '3.14159'; > say $stringy.^name; > # Str > say $stringy.^mro; > # ((Str) (Cool) (Any) (Mu)) > > The list returned from checking $stringy is the same as just > checking (Str): > > $stringy.^methods > (Str).^methods > > And it includes none of the (Cool) methods: > > (Cool).^methods > > For example, trig functions like "cos" are part of the (Cool) > list, but are not in the $stringy.^methods list, though you can > call clearly them: > > say $stringy.cos > -0.99964793 > > I guess this seems to work to give you the full list of available > methods: > > $stringy.^methods(:all)
What does ^methods really tell you?
I originally thought that $var.^methods gave you a list of all available methods on $var, but it looks like it doesn't (always?) report on inherited methods. my $stringy = '3.14159'; say $stringy.^name; # Str say $stringy.^mro; # ((Str) (Cool) (Any) (Mu)) The list returned from checking $stringy is the same as just checking (Str): $stringy.^methods (Str).^methods And it includes none of the (Cool) methods: (Cool).^methods For example, trig functions like "cos" are part of the (Cool) list, but are not in the $stringy.^methods list, though you can call clearly them: say $stringy.cos -0.99964793 I guess this seems to work to give you the full list of available methods: $stringy.^methods(:all)
