Good to know.  Perhaps I am using the wrong method.  If I can't find a  
better one, however, I will simply override fromExpression().  I have  
to think about it a bit.

Yes, I agree that the code is correct as it is now --- it's not  
obvious what the relation between constructorFromUse() and the  
generated object is.  I guess I will simply need to refactor the  
inference code so it can be used from multiple contexts.

thanks for your help,
