Can you tell me what the structure of DoLambda is so that I can  
update NodeExp.hs to deal with it... hat-check says it has no  
pointers except for source position, and parent... But I'm guessing  
that's rubbish as you said hat-check doesn't deal with it right, and  
there doesn't appear to be any way to get to the rest of the trace if  
that is true.
