I think this is a good idea that would improve things. I think, however, 
it would be troublesome to implement because expressions are typed 
bottom-up. The need here is to "teleport" type information from the 
assignment node to the addition node, which is downwards. And I'm not 
sure how this would generalize to other operators beyond "=".
