Hm, then how do you explain this:

    expression(aa = 1,
        bb = 2)   
    
    list(aa = 1,
         bb = 2)
    
One more argument for removal :) At the end it's just a function
call. Why would it be so special?

So is that a bug or not? I didn't really understand your comment in the
other mail.
