Where does it state that
$ p6 '"a b c d e".words(3).say;'
(a b c)
means the first three words, starting at zero?
https://docs.perl6.org/routine/words#class_Str says it returns "the same
as a call to |$input.comb( / \S+ /, $limit )| would".
https://docs.perl6.org/routine/comb#class_Str says it "returns a list of
non-overlapping matches limited to at most |$limit| matches".
It doesn't say it returns the first such matches; maybe it should.
It doesn't say "starting at zero", but then, why should it? The
first three wouldn't be the first three if it skipped any, right?

Where does
multi method words(Str:D $input: $limit = Inf --> Positional)
state that I can do such?
It doesn't.
https://docs.perl6.org/language/operators#postcircumfix_[_] does.
I ask this because not all methods will take []
Sure they will. They might give you runtime errors, if the method
doesn't (at runtime) return something that does Positional, but they
will all take it.
Also, where is it stated that
$ p6 '"a b c d e".words(3)[ 2, 4 ].say;'
(c Nil)
will send the first three words to [2,4] ?
It doesn't. It shouldn't: There's no "sending".
https://docs.perl6.org/language/operators#postcircumfix_[_] tells you it
calls postcircumfix:<[ ]> with a first argument of what the returned
(the first three words) and the remaining positional arguments 2, 4.

Hi Eirek,
Curt Explained it to me. Thank you for all the help!
The only thing I am hanging on is "$limit = Inf"
