1) why is it "$needle" and not "$!needle" on line 338?
Is this because it is an internal variable and not
a variable from the class declaration?
Got it
It's a parameter from line 337. If that's what you mean by
"an internal variable", then yes. :)
Apparently some other programming language do not give your
the option of internal variables in side class declarations:
everything is visable
2) where is variable ".value" defined on line 338?
What kind of variable is .value?
I don't see a `.value`, only a `$!value`. But if I did, and had that
sort of name, it would typically be a method call that returns an
attribute of the same name -- like `$!value`.
Is this .self with a better name?
3) the first "Str:D" goes to what on line 337? To .value?
No, to the invocant.
Would you define "invocant" so I stop guessing?
4) Is .value the default, if there is no name given?
I don't see a `.value`, nor what you mean by "name".
