Does it really matter where '%% write data' appears in the class? I  
currently have that code on its own line outside of any method but  
still inside the class definition.

BTW, I just tried it and it worked! I realize this is probably a ruby- 
specific question, but why did it work when I moved that line to the  
class initializer but nowhere else?
