No, I understand this, and it makes sense... why isn't it a parse error?  
It doesn't seem like you should be able to drop arbitrary parens in the 
source just anywhere you please.  IE,

   +20) / 2)

should produce a parse error, n'est pas?  Why, then, should the above code 
be interpreted as it is?  Parenthesis should have the highest precidence of 
any element... don't they?
