Break a string into whitespace-separated words:
eval: words "the quick brown fox";
["the", "quick", "brown", "fox"]
Same, using an abbreviated syntax (dot__qquotes):
eval: ."the quick brown fox";
["the", "quick", "brown", "fox"]
Ditto, a bit more laboriously:
eval: tokens char::is_space "the quick brown fox";
["the", "quick", "brown", "fox"]
