the words method is extracting items from an input string. The
$limit parameter tells the words method to extract not more than
$limit items from the string. Setting the default to Inf only tells
the method to extract as many items as it can from the input (i.e.
to process the whole string), without any limit. But since the input
string cannot be infinite, the number of items will also not be
infinite. So, the Inf default for $limit just states that there is
no limit, but you'll never get an infinity of items from a
non-infinite string.
There's no Inf default now in the definition (after latest code
changes), and it's been changed in the documentation accordingly. It's
left in the examples, however (since that "default" is in the code too,
and is tested in roast), but that can be eliminated if it leads to
confusion.

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"
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)
This would keep with the subroutine rules for the declarations
of optional variables.
