Ah!  I tried printing everything but that -- the obvious thing. Ok, so 
the multiple args are converted to one string with bars between and 
somehow that ends up as an array of space-separated args in '@'.  I 
think I'm missing something important, I can't recall any such thing 
with bars like that.  zsh knows that the pattern expands to parameters 
too, I'm ... I guess the pattern isn't expanded until we know were 
within the $parameters ... yeah, so that's fine.  But I'd better get 
this 'bars' thing straight.
