1) why is it a "method" and not a "function"?
methods are all on instance of a Class (or Role) they can locally access
the instances data via self or $ or ... see below.
1-1/2) why is there a color after a$? What happens to $a?
You can as an extra option give your instance object a different name, you
seperate that from the rest of the args with a :
2) What is an "invocant"? Does it mean I can access it
by placing it after something with a dot? Sort of
like
contains("abc", "b")
"abc".contians("b")
The incovant is the object you invoke the method on. It's the thing that
gets assigned to self, $ (and whatever else you want to call it)
3) What makes the "invocant" special over the other second
and third parameters?
See about
> class Foo {
4) I see no class called "Foo" over on
https://docs.perl6.org/type.html
That's a class being defined for this example
5) Are they creating a new class? If so, why?
To make an example
> method whoami($me:) {
6) where is @b and %c?
In this case thet aren't being passed.
> "Well I'm class $me.^name(), of course!"
7) why is there a caret in front of "name"?
There are certain Meta Object methods that are access with a ^ infront of
the name. I'd need to check the exact definition though.
Please note the Perl5 docs have had decades of people working on them the
Perl6 ones.... less so. There's bound to be some difference in scope.
