malcolm 2005/04/17 06:44:31 PDT Modified files: src/hattools HatStack.hs HatTrail.hs SExp.hs VSExp.hs Log: Tidy up SExp code, in particular to put back necessary parentheses in pretty-printed expressions. Also, do not store the result of an if/case/guard unless needed (by hat-anim), since storing it unnecessarily leads to unbounded resource usage in the other tools.
