I also find the following incredibly disturbing:
     

perl6 -e "$x = 'cat'|'dog'; say $x;"
       

dog
cat
     

Would that happen though?  What's the signature of C<say>? I think
it's something like 
	multi sub *say ($stream = $*OUT: *$data) { ... }
so autothreading wouldn't happen anyway as S9 says the slurpy array/hash
aren't autothreaded.  
   

I reread S09, and I believe "autothreading" is the wrong term for the 
iteration that a junction incurs (Even though it appears in the section 
immediately after Junctions. Autothreading is  something far weirder, 
dealing with partial dimensional slices, I believe. And in that case, it 
makes sense to turn off autothreading for slurpys, since in flattening, 
you get rid of the messy dimensions. Therefore I suspect that the above 
is wrong, and the behavior of C<say 'cat'|'dog'> is still to duplicate.
