Here's a thought. :-)

Start by splitting the 'tree' type into a 'code tree' type and a 
'declaration tree' type.  The confusion between these two seems to me to 
cause the most trouble. :-(  They're also the two which actually need 
some type of arbitrarily deep, polymorphic data structure; nothing else 
does.  Convert everything which isn't one of these (shouldn't be too 
much) into other types.

For the first pass, the 'code tree' and 'declaration tree' types can be 
intermungable to a certain extent, and we can try to disentangle them 
bit by bit.
