The easy answer to the question of "how does J form words" involves
passing the string in question to ;:
;: 'do. for. p. p.. *. . .: ..'
+---+----+--+---+--+-+--+--+
|do.|for.|p.|p..|*.|.|.:|..|
+---+----+--+---+--+-+--+--+
Personally, I would classify . in tokens pretty much
the same way I would classify it in numbers. Except,
of course, numbers typically continue on when other
kinds of words would end.
