But then it gets *BETTER*!  Assuming bancus is right:


To parse: "lo'u mi le'u si lo'u mi le'u"       

You do step "c" of the preprocessing                         

LOhU any_words_697{mi} LEhU si LOhU any_words_697{mi} LEhU   

Then you do step "e", "si" erases LEhU and then you have                                            

LOhU any_words_697{mi} LOhU any_words_697{mi} LEhU           

Now, theoretically this is one big, long lo'u...le'u string.

But the grammar as writen will not accomodate it.


Of course, my grammar will.  :-)
