How is this functionally any different from using $gettok()? The only thing I can think of is possibly a meagre - probably non-existent - speed advantage. The main use of /tokenize (in my experience) is to either make it possible to rewrite $n to effectively change the parameters as the following code sees them, or to take advantage of $* - neither of which apply to your suggestion.
I dunno, just seems like another way of doing something that's already possible.
