I've spent a lot of time looking through response.py, spyce.py, 
spyceCompile.py, etc. and I can't figure out what's going wrong here. 
Maybe I'm doing something wrong? It looks like MyOut's writeStatic() 
and writeExpr() are never called directly; only write is called 
directly. For instance, using this version of MyOut, I see only !w! and 
!/w! added to the output stream:

class MyOut:
     def __init__(self, out):
         self.out = out

     def writeStatic(self, s):
         self.out.write("!s!" + s + "!/s!")

     def writeExpr(self, s):
         self.out.write("!e!" + s + "!/e!")

     def write(self, s):
         self.out.write("!w!" + s + "!/w!")

     def flush(self):
         pass


This is despite the fact that this Spyce code --
    <p>[[="<Dimmesdale!>"]]</p>

-- compiles to this:
     response.writeStatic('\n\n<p>')
     response.writeExpr('<Dimmesdale!>')
     response.writeStatic('</p>\n\n</body>\n</html>\n')


Suggestions?

Thanks
Philip
