Hi JJ,
I am confused. I thought that
$limit = Inf
used in
multi method words(Str:D $input: $limit = Inf --> Seq)
meant that the default was "Inf"
It's not now: https://docs.perl6.org/routine/words#class_Str
Also, it is not stated that $limit is optional. I would
propose adding a "?" to the end of $limit:
multi method words(Str:D $input : $limit? = Inf --> Seq)
That's not how it's defined. There are two forms in the method, which
effectively could be resumed to a single one
method words(Str:D: $limit?)
But that's simply not how it's defined in the source. The fact that
there are two multis indicate quite clearly that $limit is optional, but
if that's not enough, the examples should clarify that.
Cheers

Would it not be much more readable to only have one line?
I personally get lost if there are more than two lines.
