Hi All,

is no help
Not to ask too obvious a question, but why does words use a []
instead of a () ?

Are you referring to a particular example? I can't find it.
yes the ones in the original post.
At any rate, $whatever.words[4] is the same as $whatever.words()[4].
That method needs no arguments, so it makes do without parentheses. When
it uses it, it's to limit the number of words returned.

I am confused as to when to use [] and when to use () with a method.
The only thing can think of is that [] allows me to do thing like
[4]
[4,6]
[4..6]
Where I can't do it with ()
But why is (4) different than [4]?
And
https://docs.perl6.org/routine/words#class_Str
(Str) routine words
multi sub words(Str:D $input, $limit = Inf --> Positional)
multi method words(Str:D $input: $limit = Inf --> Positional)
Also is `Str:D $input:` written correctly? I have only seen it as
`Str:D:` before.
