My original idea was to write a semantic diff tool that just does some simple things up front: create an MD5 from all top level blocks of the code. Start by just finding matching blocks of code ('{' and '}', '(' and ')') and remember the source locations for these and their MD5 values. Run a normal diff on the code and see what blocks the diffs fall into. Then try
