Not quite correct - *some* folding is still needed in Java:

http://java.sun.com/docs/books/jls/second_edition/html/expressions.doc.html#5313

As Mark points out for C++, writing a java_fold() for these
ought to be simple and we can avoid calling fold() altogether
before semantic analysis has finished.

I know Tom would be very happy with this scheme. :-)
